Detector Front End Electronics

The operational amplifier (see Fig. 4) in the fan-out, the OPA350, is a single-supply rail-to-rail amplifier functioning from 0-5 volts. Its behaviour at cryogenic temperatures (77 K) is adequate for this application and it has proven to be reliable and repetitive after many thermal cycles.
