DDC114 Overview
The DDC114 is a 20-bit, quad channel, current-input analog-to-digital (A/D) converter. It bines both current-to-voltage and A/D conversion so that four low-level current output devices, such as photodiodes, can be directly connected to its inputs and digitized. For each of the four inputs, the DDC114 provides a dual-switched integrator front-end.
