Sumario:A wide dynamic range multi-gain transimpedance amplifier custom integrated circuit has been developed for the readout of avalanche photodiode and vacuum photodiode in the CMS electromagnetic calorimeter for LHC experiment. The 92 db input dynamic range is divided into four ranges of 12 bits each in order to provide 40 MHz analog sampled data to a 12 bits ADC. This concept, which has been integrated in rad-hard full complementary bipolar technology, will be described. Experimental results obtained in lab and under irradiation will be presented along with test strategy being used for mass production. 6 Refs.
