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 (0.05V/C 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. FEATURES Low Offset Voltage Drift Low Offset Voltage Operating Voltage High Voltage Gain CMR, SVR Operating Current Output Full-Swing (RL=10k) Shutdown Ground Sensing Package Outline PACKAGE OUTLINE

(Note 1) For supply voltage less than 11V, the absolute maximum input voltage is equal to the supply voltage. (Note 2) On the PCB " EIA/JEDEC (76.2x11.43x1.6mm, two layers, FR-4) " (Note 3) Do not exceed "Power dissipation: PD" in which power dissipation in IC is shown by the absolute maximum rating.
