Abstract :
A 32 channel analog VLSI detector readout chip (HARP32) with an input charge preamplifier, a 64-cell current integrating analog memory in each channel and a common analog multiplexer, has been used in a test beam with segmented silicon detectors. The device was operated at the LHC clock speed of 66 MHz. The different pedestal variations seen at the output are analyzed: the input noise σn amounts to 2.8mV r.m.s., the pedestal non-uniformity in channel σped to 1.2 mV r.m.s., the channel to channel pedestal variation σch to 4.0 mV r.m.s., and an output baseline shift σobs of 3.5 mV r.m.s has been observed
