Overview

The ISL70227SRH 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 ISL70227SRH the ideal choice for applications requiring both high DC accuracy and AC performance. The combination of precision, low noise, and a 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, precision power supply controls, and industrial controls. The ISL70227SRH is available in a 10 Ld hermetic ceramic flatpack and operates over the extended temperature range of -55 °C to +125 °C.
