36V Rad Hard Dual Precision Operational Amplifier

ISL70227SEH

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.
