Abstract :
In this paper we present an integrated circuit designed for PMT pulse processing. This circuit was developed for the RICH detector of the AMS experiment. It integrates 16 identical channels and have to deal with spatial constraints (low power consumption, radiation hardness). It processes the 16 analog signals coming from anodes of a multi-anode PMT and the signal coming from a dynode. It integrates a control logic for the output multiplexing, a test mode that can be activated for the calibration of each channel and an offset cancellation system has been designed for the dynode channel. This offset cancellation is important in order to cancel thermal drifts and offset spreads.
