ADG4612/adg4613 rev. 0 | page 17 of 24 theory of operation the ADG4612/adg4613 contain four independent single- pole/single-throw (spst) switches. each switch is rail-to-rail and conducts equally well in both directions when on. the ADG4612/adg4613 has two modes of operation: normal mode and isolation mode. the operation modes are made possible by a special detection circuitry that monitors the voltage levels at the source or drain terminals and v dd relative to ground. depending on these voltage levels, the device operates in normal mode or isolation mode accordingly. isolation mode is a useful feature that isolates the inputs from the outputs where input signals may be present before supplies or during positive fault conditions that can occur in applications. normal mode in normal mode, the switch functions as a normal 4 spst switch, whereby the switch is controlled by the logic input pins, in1 to in4. the following three conditions need to be satisfied for the switch to be in the on condition; ? v dd 2.7 v; and ? input signal, v s , v d < v dd + v t ; and ? logic input, inx set to on level when the switch is in the on condition, if the signal range is from v dd to ?5.5 v, the signals present on the switch inputs are passed through to the switch output. if the analog input exceeds v dd by a threshold voltage, v t , the switch turns off and is in isolation mode. if the analog input signal exceeds the negative supply, v ss , when the switch is off, the switch blocks a signal up to ?5.5 v. if the switch is on, the switch remains on, and this signal is passed to the output. see the negative fault condition; negative signal handling section for more details. isolation mode in isolation mode, all switches are in the off condition. the switch inputs are isolated from the switch outputs. the switch inputs are high impedance inputs with greater than 475 k impedance to v dd ground and across the switch. this prevents any current from flowing that can damage the switch. this is very useful in applications where analog signals may be present at the switch inputs before power is present or where the user has no control over the power supply sequence. the switch is in isolation mode when ? no power supplies are present, that is, when v dd is floating or v dd 1 v; or ? input signal, v s , v d > v dd + v t the negative supply rail, v ss , can be floating or 0 v to ?5.5 v. the ground pin must be connected to the ground potential. table 11. switch operation mode v dd v ss 1 gnd v s , v d (input voltage, s or d) switch condition switch mode floating x 0 v ?5.5 v to +10.5 v all switches off isolation 0 v to 16 v inputs isolated from outputs 0 v to 0.8 v x 0 v ?5.5 v to +10.5 v all switches off isolation 0 v to 16 v inputs isolated from outputs v dd 2.7 v x 0 v v s , v d > v dd + v t all switches off isolation inputs isolated from outputs v dd 2.7 v to 16 v 0 v to ?5.5 v 0 v v dd to v dd C 16 v switch state is determined by logic levels, inx normal 1 x = dont care; for example, floating, 0 v to ?5.5 v. ADG4612/adg4613 rev. 0 | page 18 of 24 bipolar operation and single-supply operation the ADG4612/adg4613 have a maximum operational range from v dd to v ss of 16 v. the maximum signal range from source to drain, v s to v d , is also 16 v. during operation of the device, the signal range can exceed the power supply rails, but the voltage between the most negative voltage on the device (v s ,v d or v ss ) should be within 16 v of the most positive voltage (v s , v d , inx, or v dd ). these voltage ratings should be adhered to at all times for guaranteed functionality. see table 5 for guaranteed supply ranges. signal ranges and power supply ranges exceeding 16 v may affect the long-term reliability of the device. the ground pin must always be connected to the gnd potential to ensure proper functionality in isolation and normal operation mode. the minimum v dd voltage that the part is guaranteed operational is 2.7 v. the maximum recommended v dd voltage is 16 v. the minimum supply voltage recommended on v ss is ?5.5 v, and the maximum voltage allowable on v ss is 0 v. therefore, given that the v dd to v ss range is 16 v maximum when, v ss = ?5.5 v, the v dd = +10.5 v maximum. positive fault condition if the analog input exceeds v dd by a threshold voltage, v t , then the switch turns off and is in isolation mode. the part can handle a fault of up to 16 v, referenced to the most negative signal. for example, if v dd = 5 v, v ss = 0 v, then the switch protects against an overvoltage of up to 16 v. if v ss = ?5 v and v dd = +5 v, then the switch protects against an overvoltage of up to +11 v. negative fault condition; negative signal handling the ADG4612/adg4613 are not damaged if the analog inputs exceed the negative supply, v ss . if the switch is in the off condition, the switch blocks a signal up to ?5.5 v. if the switch is in the on condition, the switch remains on, and the negative signal is passed to the output; therefore, the ADG4612/adg4613 can pass a negative signal up to ?5.5 v with v ss = 0 v. the user must ensure that the downstream circuitry can handle this signal level. also, the user should ensure the voltage between the most negative voltage on the device (v s ,v d or v ss ) is within 16 v of the most positive voltage (v s , v d , inx, or v dd ). ADG4612/adg4613 rev. 0 | page 19 of 24 applications information there are many application scenarios that benefit from the functionality offered on the ADG4612/adg4613 switches. the ADG4612/adg4613 offer power-off protection, ensuring the switch is guaranteed off and inputs are high impedance with no power supplies present. this isolation mode is a useful feature that isolates the inputs from the outputs where input signals may be present before supplies. the isolation mode also protects the system against positive fault conditions that can occur in applications, ensuring that the switch turns off and protects downstream circuitry. for example, a module can be connected to a live backplane, supplying signals to the board before supplies are present. this is common in hot swap applications where a card could be hot plugged in a shelf where there are others cards already working and powered on. the ADG4612/adg4613 allow negative signals, down to ?5.5 v to be passed without a negative supply. this can be very useful in applications that need to pass negative signals but do not have a negative supply available. this cannot be done with conventional cmos switches because esd protection diodes turn on and clamp the signals. theses features ensure the system is very robust to power supply sequencing issues that can be present in conventional cmos devices. 09005-030 live backplane hot swap modules controller hot swap modules hot swap modules power supply sw figure 32. typical application signals on inputs with no power present in conventional cmos switches, esd protection diodes can be found on the analog and digital inputs to v dd and gnd or v ss (see figure 33 , for example). if an input voltage is present on the switch inputs with no power supplies applied, current can flow through the esd protection diodes. if this current is not limited to a safe level, it is possible to damage the esd protection diodes and, hence, the switch. input signals may pass through the switch to the output affecting downstream circuitry. the user may also be exceeding the absolute maximum ratings of the devices, and, therefore, affecting the long-term reliability of the device. v s v ss v dd r s r l sx gnd forward current v s > v d forward current flows load current dx 09005-031 figure 33. esd protection diodes on conventional cmos switch some users add external diodes or add current-limiting resistors to protect the device against the conditions shown in figure 33 . however, these solutions all have disadvantages in that they add extra board area, extra component count, and cost. the system level performance can also be affected by the higher on resistance from the current-limiting resistors or the higher leakage from external schottky diodes. using external diodes for protection still creates the problem where a floating v dd line can be pulled up to a diode drop from the input signal. v s v ss v dd r s r l sx gnd dx 09005-032 forward current load current v s > v d forward current flows figure 34. external protection added to protect switch against damage if signals present on inputs without power supplies the ADG4612/adg4613 eliminate the concerns shown in figure 34 . there are no internal esd diodes from the analog or digital inputs to v dd or v ss . if signals are present on the ADG4612/ adg4613 inputs before power is present, the switch is in isolation mode, which means that the inputs have high impedance to v dd , gnd, and the output. this prevents current flow and protects the device from damage. ADG4612/adg4613 rev. 0 | page 20 of 24 power supply sequencing another benefit of the ADG4612/adg4613 is it eliminates concerns about the power supply sequence. the part can be powered up in any sequence without damage. for devices with conventional cmos switches, it is recommend that power supplies are powered up before analog or digital inputs are present. the ADG4612/adg4613 do not have any power supply sequencing requirements, thereby making them a very robust design. however, a ground must first be present for the device to function in isolation mode and normal mode. v dd supply another area of concern with conventional cmos switches that have analog signals present before the part is powered up is that the v dd supply can be pulled up through the internal esd protection diodes. the v dd supply normally gets pulled up to the input voltage level minus a diode drop, v dd ~v s , v d ? v diode . this voltage can be high enough to power up other chips that are connected to this supply rail in a system, potentially damaging other components in that system. the ADG4612/adg4613 architecture ensures that the v dd supply is isolated from the analog inputs, thereby preventing the supplies from being pulled to a higher potential when a signal is present on the inputs without any power having been applied.
