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.
