ISL70219ASEH

40V Radiation Hardened and SET Enhanced Precision Low Power Operational Amplifier

Product Status: Mass Production

OVERVIEW

The ISL70219ASEH is a very high precision amplifier featuring the perfect combination of low noise vs power consumption. The ISL70219ASEH’s low offset voltage, low IBIAS current, and low temperature drift make it the ideal choice for applications requiring both high DC accuracy and AC performance. The combination of high precision, low noise, low power, and a small footprint provides outstanding value and flexibility relative to similar competitive parts

Applications for these amplifiers include precision active filters, medical and analytical instrumentation, precision power supply controls, and industrial controls.

The ISL70219ASEH is offered in a 10 Ld hermetic ceramic flatpack. The device is packaged in industry standard pin configurations and operates across the extended temperature range from -55°C to +125°C.
