# Performance of a low noise readout ASIC for the W-Si calorimeter physics prototype for the future linear collider

Abstract : An ASIC (FLC_PHY3) has been developed to readout the test-beam prototype of the future linear collider Tungsten-Silicium calorimeter. It consists of 18 channels low noise charge amplifiers, bi-gain $CRRC^2$ 180 ns shapers, 12bit track and hold and 5 MHz output multiplexer. It covers a dynamic range of 15 bits with a noise of 3500 e- with the 70 pF detector and a linearity at the per-mil level. The preamplifier gain can be adjusted from 0.3 V/pC to 5 V/pC to accomodate various future detectors. The chip dissipates 7 mW/channel and 1000 chips have been produced in AMS $0.8 \mum$ BiCMOS technology.
