DDC1128 Overview
The DDC1128 is a 20-bit, 128-channel, current-input analog-to-digital (A/D) converter. It bines both current-to-voltage and A/D conversion so that 128 separate low-level current output devices, such as photodiodes, can be directly connected to its inputs and digitized. For each of the 128 inputs, the DDC1128 uses the proven dual switched integrator front-end.
