ISL70417SEH

Radiation Hardened 40V Quad Precision Low Power Operational Amplifiers

OVERVIEW

The ISL70417SEH contains four very high precision amplifiers featuring the perfect combination of low noise vs power consumption. Low offset voltage, low IBIAS current and low temperature drift making them the ideal choice for applications requiring both high DC accuracy and AC performance. The combination of high precision, low noise, low power and small footprint provides the user with 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 ISL70417SEH is offered in a 14 Ld hermetic ceramic flatpack package. The device is offered in an industry standard pin configuration and operates across the extended temperature range from -55°C to +125°C.
