NJU7098
Auto-Zero, High Precision Single Operational Amplifier
GENERAL DESCRIPTION
The NJU7098 is Auto Zero high precision operational amplifiers
available in the SOT-23-5 packages. The NJU7098 operates from a
single 3V to 10V supply. The NJU7098 of CMOS operational amplifier
use Auto Zero techniques to simultaneously provide very low offset
voltage, and near-zero drift over temperature (0.05µV/ºC Max.).
The NJU7098 includes a shutdown mode. Under logic control, the
amplifiers can be switched from normal operation to a standby. When the
SHDN pin is connected high, the amplifier is active. Connecting SHDN
low disables the amplifier.
