| NJM2737 Low Noise Low Supply Voltage Dual Operational Amplifier with Full Swing Input and Output s GENERAL DESCRIPTION NJM2737 is a single supply dual operational amplifier with full swing input and output, operates from 1.8V. Noise characteristic is designed low as conventional low noise operational amplifiers, such as NJM5532 and NJM4580. It is suitable for PC audio, portable audio and other low voltage single supplied audio applications. s PACKAGE OUTLINE NJM2737D NJM2737M s FEATURES q Operating Voltage q Low Input Voltage Noise q Gain Band Width product q Slew Rate q Offset Voltage q Input Full-Swing q Output Full-Swing q Load Drivability q Bipolar Technology q Package Outline s PIN CONFIGURATION 1.8 to 6.0V 5nV/Hz typ. + 3.1MHz typ. at V =5V,RL=2k + 0.7V/s typ. at V =5V,RL=2k 5mV max + VICM= 0 to 5.0V at V =5V + VOH 4.9V/ VOL 0.15V at V =5V,RL=20k + VOH 4.75V/ VOL 0.25V at V =5V,RL=2k DIP8,DMP8,SSOP8,TVSP8 NJM2737V NJM2737RB1 PIN CONFIGURATION 1 2 3 8 7 6 5 1.OUTPUT1 2.-INPUT1 3.+INPUT1 4.V 5.+INPUT2 6.-INPUT2 7.OUTPUT2 + 8.V 4 Ver.2004-02-24 -1- NJM2737 s ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Differential Input Voltage Input Common Mode Voltage Range Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL + V VID VICM (Ta=25C) RATINGS UNIT 7.0 V 1.0 V 0 to 7.0 500(DIP8) 300(DMP8) 250(SSOP8) 320(TVSP8) -40 to +85 -40 to +125 V PD Topr Tstg mW C C (Note1) + + If the supply voltage ( V ) is less than 7V, the input voltage must not over the V level through 7V is limit specified. s RECOMMENDED OPERATING CONDITION PARAMETER Supply Voltage SYMBOL + V (Ta=25C) RATING UNIT 1.8 to 6.0 V s ELECTRICAL CHARACTERISTICS q DC CHARACTERISTICS PARAMETER Operating Current Input Offset Voltage Input Bias Current Input Offset Current Voltage Gain Common Mode Rejection Ratio Supply Voltage Rejection Ratio Maximum Output Voltage1 (V =5V,Ta=25C) TYP MAX UNIT 1200 1 200 5 85 70 85 4.95 0.05 4.85 0.15 1600 5 800 100 0.1 0.25 5 V V A mV nA nA dB dB dB V + SYMBOL ICC VIO IB IIO AV CMR SVR VOH1 VOL1 TEST CONDITION No Signal MIN - RL=2k CMR+:2.5VVCM5.0V, CMR-: 0VCM2.5V(Note2) V /GND = 2.0 to 3.0V + 60 55 70 4.9 4.75 - RL=20k RL=20k RL=2k RL=2k Maximum Output Voltage 2 VOH2 VOL2 Input Common Mode Voltage VICM CMR>55dB 0 Range (Note2) CMR is represented by either CMR+ or CMR- which has lower value.
