TID Performance Test Summary

The 5901 Quad Op Amp is well suited for
applications up to 300KRad and is capable of
serving missions up to and above 10MRad(SiO2).

The most significant performance parameter shifts are:
– A maximum change in offset voltage of 2 to 3mV
– Stable gain up to 10MRad
– Slew rate of approximately <10% at 300KRad

A statistically significant number of devices were
characterized in total dose environments. >32 amplifiers.

Exposure up to 10MRad(SiO2).

Data demonstrated this series of Analog Building Blocks
meets or exceeds the requirements of a majority of
missions

Future Testing: SEE, SEL, Prompt Dose
