Ultra Low Noise, < 280 electrons rms
Model A225 is a high performance thin film hybrid charge sensitive preamplifier and shaping amplifier developed especially for high resolution systems employing solid state detectors, proportional counters, photomultiplier tubes and other charge producing detectors in the pulse height analysis or A/D mode of operation.
While these units were specifically designed for satellite instrumentation, the following unique characteristics make them equally useful for space, laboratory and commercial applications:
