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. ■FEATURES ●Low Offset Voltage Drift ●Low Offset Voltage ●Operating Voltage ●High Voltage Gain ●CMR, SVR ●Operating Current ●Output Full-Swing (RL=10kΩ) ●Shutdown ●Ground Sensing ●Package Outline ■PACKAGE OUTLINE NJU7098F1 0.05µV/ºC max. 15µV max. +3V to +10V 140dB typ. 130dB typ. 0.6mA typ.
