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.

A data readout integrated circuit comprising a plurality of readout channels coupled to detectors through a plurality of detecting channels for providing readout signals at an output, each readout channel of said plurality of said readout channels comprising:
- a means for receiving one detector signal;
- a charge sensitive amplifier coupled to said receiving means for integrating said detector signal and outputting a voltage signal;
- a shaper amplifier for providing shaped signal responsive to said voltage signal;
- and
- a means for outputting one of said readout signals responsive to said shaped signal from said shaper amplifier.
The data readout integrated circuit comprising a plurality of readout channels coupled to receive detected signals from detectors through a plurality of detector channels, respectively, each integrated circuit channel comprising:
- means for receiving one of said detected signals;
- a charge sensitive amplifier coupled to said receiving means for integrating one of said detector signals and outputting a voltage signal;
- and
- a means for a peak hold circuit for holding a peak of the voltage signal and outputting for outputting a peak hold signal as a readout signal.
