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.
