Overview
The CCD55-30 is one of the CCD55 range of very large area CCD image sensors primarily intended to suit the requirements of astronomy, medical diagnostic and scientific measuring instruments. Standard three-phase clocking and buried channel charge transfer are employed. The device operates in the inverted mode for minimum dark current. The readout register has a high performance low noise amplifier at one end for slow-scan applications and a high speed amplifier at the other end. The image area is split into two sections which can be clocked separately for frame transfer operation.
The CCD55-30 is an upgraded version of the CCD05-30 with improved output amplifiers and is also available in backthinned format. The CCD55-30 is pin compatible with the CCD05-30, except that the top two amplifiers are not provided.
The CCD55-30 scientific image sensor is primarily specified for operation in a full-frame imaging mode with slow-scan readout from the whole image area through the low noise amplifier and is tested at a temperature of approximately 253 K.
