NJM2737VTE1
NJM2737 Low Noise, Rail-to-Rail Input/Output Dual Operational Amplifier ■ GENERAL DESCRIPTION NJM2737 is a Rail-to-Rail Input/Output dual operational amplifier featuring Low power, low noise and operation from 1.8V. Noise characteristic is designed low as conventional low noise operational amplifiers, such as NJM5532 and NJM4580. NJM2737 is suitable for PC audio, portable audio and other low voltage single supplied audio applications. ■ FEATURES ● Operating Voltage ● Low Input Voltage Noise ● Gain Band Width product ● Slew Rate ● Offset Voltage ● Rail-to-Rail Input ● Rail-to-Rail Output ● Load Drivability ● Bipolar Technology ● Package Outline ■PACKAGE OUTLINE NJM2737D NJM2737V 1.8 to 6.0V 5nV/√Hz typ. 3.1MHz typ. at V+=5V,RL=2kΩ 0.7V/µs typ. at V+=5V,RL=2kΩ 5mV max VICM= 0 to 5.0V at V+=5V VOH ≥ 4.9V/ VOL ≤ 0.15V at V+=5V,RL=20kΩ VOH ≥ 4.75V/ VOL ≤ 0.25V at V+=5V,RL=2kΩ NJM2737M NJM2737RB1 DIP8,DMP8,SSOP8,TVSP8 ■ PIN CONFIGURATION PIN CONFIGURATION 8 1 2 − 7 ＋ 6 3 ＋ 4 Ver.2009-03-04 − 1.OUTPUT1 2.-INPUT1 3.+INPUT1 4.V5.+INPUT2 6.-INPUT2 7.OUTPUT2 8.V+ 5 -1- NJM2737 ● TRANSIENT CHARACTERISTICS PARAMETER Slew Rate ● DC CHARACTERISTICS PARAMETER SYMBOL SR SYMBOL Operating Current ICC Input Offset Voltage TEST CONDITION RL=2kΩ TEST CONDITION - MIN 0.7 - V/µs (V+=3V,Ta=25°C) TYP MAX UNIT - 1000 1500 µA VIO - 1 5 mV IB - 200 800 nA Input Offset Current IIO - 5 100 nA Voltage Gain AV RL=2kΩ 60 85 - dB CMR+:1.5V≤VCM≤3.0V, CMR-: 0≤VCM≤1.5V(Note3) 48 63 - dB dB Input Bias Current No Signal MIN (V+=5V, Ta=25°C) TYP MAX UNIT Common Mode Rejection Ratio CMR Supply Voltage Rejection Ratio SVR V+/GND = ±1.2 to ±2.0V 68 83 - VOH1 RL=20kΩ 2.9 2.95 - VOL1 RL=20kΩ - 0.05 0.1 VOH2 RL=2kΩ 2.75 2.85 - VOL2 RL=2kΩ - 0.15 0.25 Maximum Output Voltage1 Maximum Output Voltage 2 Input Common Mode Voltage VICM CMR>48dB 0 Range (Note3) CMR is represented by either CMR+ or CMR- which has lower value.
