ISL70219ASEH

40V Radiation Hardened and SET Enhanced, Precision Low-Power Operational

Amplifier

DATASHEET

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.
