A FULLY PROGRAMMABLE 16-CHANNEL SPECTROSCOPY AMPLIFIER IN A SINGLE NIM UNIT

A high-performances 16-channel spectroscopy amplifier having high perf ormances has been developed in a single width NIM unit, The pole zero cancellation, the coarse and fine gain, the shaping time, the output p olarity and the output DC offset can be adjusted through a serial inte rface. The selected values are stored in a non-volatile memory. Each c hannel has three analog outputs. The first has a nearly gaussian shape with gain from 0.5 to 256 (2048 possible values), the second is a sim ilar pulse with a gain 10 times the choosen value of the first output. The last is a fast signal suitable for timing purposes.
