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 sensitive amplifier inputs with self triggering output. The trigger threshold can be adjusted to provide energy discrimination. The chip has different, externally selectable, operational modes including a sparse readout mode in which only the channels which have received signals greater than a preselected threshold value are readout. The sparse readout mode results in increased data throughput, thus providing fast data acquisition capabilities.
