DDC232 Datasheet Analog-to-digital Converter

Manufacturer: Texas Instruments

Overview: DDC232 .ti. 32-Channel, Current-Input Analog-to-Digital Converter Check for Samples: DDC232 SBAS331D – AUGUST 2004 – REVISED APRIL.

General Description

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

It bines 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 DDC232 provides a dual-switched integrator front-end.
