DDC316 Analog-to-Digital Converter

The DDC316 is a 16-bit, 16-channel, current-input analog-to-digital converter (ADC). It combines both current-to-voltage and analog-to-digital (A/D) conversion so that 16 separate low-level current output devices (such as photodiodes) can be directly connected to its inputs and digitized. For each of the 16 inputs, the DDC316 provides a dual-switched integra.
