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.

(Note 4) When supply voltage is less than 7V, the absolute maximum input voltage is equal to the voltage.
(Note 5) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit.
(Note 6) On the PCB " EIA/JEDEC (76.2x114.3x1.6mm, two layers, FR-4) ".
(Note 7) Do not exceed "Power dissipation: PD" in which power dissipation in IC is shown by the absolute maximum rating.
Refer to following Figure 1 for a permissible loss when ambient temperature (Ta) is Ta≥25°C.
