ISL70227SEH

36V Radiation Hardened Dual Precision Operational Amplifier

OVERVIEW

The ISL70227SEH is a high precision dual operational amplifier featuring very low noise, low offset voltage, low input bias current and low temperature drift. These features plus its radiation tolerance, make the ISL70227SEH the ideal choice for applications requiring both high DC accuracy and AC performance. The combination of precision, low noise and small footprint provides the user with outstanding value and flexibility relative to similar competitive parts.

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

The ISL70227SEH is available in a 10 lead hermetic ceramic flatpack and operates over the extended temperature range of -55°C to +125°C.
