    July 18, 2014 36V Radiation Hardened Dual Precision Operational Amplifier
    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. Features Applications for these amplifiers include precision and
    analytical instrumentation, active filters, and power supply
    controls. Operating temperature range . .-55В°C to +125В°C The ISL70227SEH is available in a 10 lead hermetic ceramic
    flatpack and operates over the extended temperature range of
    -55В°C to +125В°C. Applications Electrically screened to DLA SMD# 5962-12223 Wide supply range 4.5V to 42V max. Very low voltage noise . 2.5nV/в€љHz, typ.
