ISL70227SRH FN7925
Rev 2.00
July 18, 2014 36V Radiation Hardened Dual Precision Operational Amplifier
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
small footprint provides the user with outstanding value and
flexibility relative to similar competitive parts. Features Applications for these amplifiers include precision and
analytical instrumentation, active filters, precision power
supply controls, and industrial controls. Low input voltage offset 10ВµV, typ. The ISL70227SRH is available in a 10 Ld hermetic ceramic
flatpack and operates over the extended temperature range of
-55В°C to +125В°C. Applications Precision Instruments Industrial Controls Wide supply range 4.5V to 36V max. Very low voltage noise . 2.5nV/в€љHz, typ.
