Overview
This version of the CCD42 family of CCD sensors has full-frame architecture, which in combination with extremely low noise amplifier, makes the device well suited for use in general scientific imaging.
The output amplifier is designed to give excellent noise levels at low pixel rates and can match the noise performance of most conventional science CCDs at pixel rates as high as 3 MHz. There are two low noise amplifiers in the readout register, one at each end. Charge can be made to transfer through either or both amplifiers by making the appropriate R∅ connections. The readout register has a gate controlled dump drain to allow fast dumping of unwanted data.
The register is designed to accommodate four image pixels of charge and a summing well is provided capable of holding six image pixels of charge. The output amplifier has a feature to enable the responsivity to be reduced, allowing the reading of such large charge packets.
