The CAEN Mod.A1422C/D is a 5 mV/MeV 8-channel preamplifier implemented into an alloy box and features SHV connectors for the DET/IN and HV/IN signals, 2 RJ45 for the differential outputs, LEMO connectors for the TEST IN and COM OUT and a cable with a D-type 9 pin male connector for the power supply. The module accepts both positive and negative input charge pulses and provide a differential output of ±5V max on 1 kΩ termination, and ±2.5V on 100 Ω back termination. A test input accepts positive and negative signals for calibration purposes. Moreover the sum of the 8 energy outputs, with 1 µs decay time, is available on the COM OUT output.
A customization is available to improve amplifier protection from transients at detector input connection.
