Abstract
A multi-channel readout chip is provided in which each channel has an analog section and a digital section. Each channel of the readout chip employs low noise charge amplifiers with self trigger and calibration capabilities to provide timing information with better than 20 nanosecond precision. The trigger threshold can be adjusted to provide energy discrimination. The chip has a sparse readout function in which only the channels which have received signals greater than a preselected threshold value are readout, thus providing fast data acquisition capabilities.
