NJU7043 High Output Current, Rail-to-Rail Input/Output Dual CMOS Operational Amplifier ■GENERAL DESCRIPTION ■PACKAGE OUTLINE The NJU7043 is a Rail-to-Rail Input/Output dual CMOS operational amplifier with a low operating voltage from 1.8V to 5.5V and high output current of 40mA which is higher than our conventional CMOS operational amplifiers. It also offers a rail-to-rail input/output between both rails, low operating current of 300μA per amplifier, low input bias current of 1pA and ground sensing, which is suitable for various applications. The NJU7043 is available in 8-lead package of DIP8, 8-lead small surface mount packages of DMP8, SOP8 JEDEC 150mil, SSOP8, MSOP8 (TVSP8) and PCSP20−CC. ■FEATURES ● Operating Voltage ● Rail-to-Rail Input/Output ● High Output Current ● Input Offset Voltage ● Wide Input Common Mode Voltage Range ● Operating Current ● High Input Impedance ● Low Input Bias Current ● Ground Sensing ● Package ■PIN CONFIGURATION ○NJU7043D,M,E,V,RB1 ( Top View ) NJU7043M ( DMP8 ) NJU7043E (SOP8) NJU7043V ( SSOP8 ) NJU7043RB1 (MSOP8(TVSP8)) NJU7043SCC (PCSP20−CC) 40mA typ.
