Description
The AD8 amplifier-discriminator is a compact, low noise, high gain electronics module designed to be used in photomultiplier photon counting systems to generate TTL output pulses. An output pulse of fixed width and amplitude is produced for each photomultiplier output pulse that exceeds the input discriminator threshold level. The threshold level is fixed to -2 mV, which is sufficiently sensitive to enable most photomultipliers with 10 or more dynodes to operate in single photon counting mode.
