An integrated front-end chip has been developed to readout the Silicon PM for the ILC analog hadronic calorimeter. It is built around a variable gain low-noise preamplifier followed by a variable peaking-time shaper (20-200 ns), track and hold and multiplexed output. This structure allows to produce single photo electron spectrum with well separated peaks for absolute calibration at fast shaping (40ns) as well as physics signals from the scintillating fibbers (up to 2000 photo-electrons) with a slower shaping (150ns) compatible with the W-Si Electromagnetic Calorimeter DAQ. Besides, an input DAC allows to tune the detector gain by varying the operating voltage by up to 5V. The chip accommodates 18 channels and 1000 circuits have been produced in 2004, the design and the measurement results of which will be presented.
