NJU7098
Auto-Zero, High Precision Single Operational Amplifier
■GENERAL DESCRIPTION
The NJU7098 is Auto Zero high precision operational amplifiers
available in the SOT23-5 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.
