DDC232 Datasheet (Texas Instruments) - Analog-to-Digital Converter

DDC232, Analog-to-Digital Converter

The DDC232 is a 20-bit, 32-channel, current-input analog-to-digital (A/D) converter.

It combines both current-to-voltage and A/D conversion so that 32 separate low-level current output devices, such as photodiodes, can be directly connected to its inputs and digitized.

For each of the 32 inputs, the
