DDC264 Datasheet (Texas Instruments) - Current-Input Analog-to-Digital Converter

DDC264, Current-Input Analog-to-Digital Converter

The DDC264 is a 20-bit, 64-channel, current-input analog-to-digital (A/D) converter.

It combines both current-to-voltage and A/D conversion so that 64 separate low-level current output devices, such as photodiodes, can be directly connected to its inputs and digitized.

For each of the 64 inputs, the
