DDC1128 Datasheet (Texas Instruments) - Current-Input Analog-to-Digital Converter

DDC1128, Current-Input Analog-to-Digital Converter

The DDC1128 is a 20-bit, 128-channel, current-input analog-to-digital (A/D) converter.

It combines 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,
