Cremat's CR-111-R2.2 is a single channel charge sensitive preamplifier module intended for use with various types of radiation detectors including semiconductor detectors (e.g. CdTe and CZT), p-i-n photodiodes, avalanche photodiodes (APDs), and various gas-based detectors. The CR-111-R2.2 is one of a series of four charge sensitive preamplifiers offered by Cremat, which differ from each other most notably by their gain. A guide to selecting the best charge sensitive preamplifier for your application can be found at our web site: http://cremat.com. As with all Cremat's preamplifier modules, the CR-111-R2.2 is less than one square inch in area, allowing for compact multi-channel detection systems to be constructed using a modular design.
