DESCRIPTION
The NJU7098A is a low offset voltage and
zero-drift operational amplifier. With an maximum
input offset voltage of 15μV and offset drift of
0.05μV/°C, The NJU7098A is suitable for applications
in which error sources cannot be tolerated.
The NJU7098A operate from 3V to 10V with single
supply. Rail-to-rail output swing , input common
mode voltage within negative rail and 30mA high
output current capability provided by the NJU7098A
make low-side sensing or precision output buffer
easy.
The almost zero DC offset and offset drift are
supported with a power supply rejection ratio and
common mode rejection ratio at 130dB. Futuremore,
typical open-loop voltage gain is 140dB.
The NJU7098 includes a shutdown mode. Under
logic control, the amplifiers can be switched from
normal operation to shutdown current that is 15μA
max and the output placed in a high- impedance
state.
The NJU7098A is available in 6-pin SOT-23
package.

(1) Differential voltage is the voltage difference between +INPUT and -INPUT.
(2) For supply voltage less than11V, the absolute maximum input voltage is equal to supply voltage.
(3) Power dissipation is the power that can be consumed by the IC at Ta=25°C, and is the typical measured value based on
JEDEC condition. When using the IC over Ta=25°C subtract the value [mW/°C]=PD/(Tstg(MAX)-25) per temperature.
