Evaluation of the multiplexer for the Cassini visible and infrared mapping spectrometer focal plane array

The multiplexer being used in the focal plane array for the Cassini Visible and Infrared Mapping Spectrometer has received extensive characterization. The multiplexer is a capacitive transimpedance amplifier line array having very low noise, and fabricated using a radiation hardened CMOS process. Details of the amplifier characteristics as well as results from multiplexer and FPA testing have been obtained. The results show that the multiplexer will be able to meet the focal plane array mission objectives.
