DDC114 - 20-Bit Analog-To-Digital Converter

General Description

The DDC114 is a 20-bit, quad channel, current-input analog-to-digital (A/D) converter.

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

Key Features

  • D SINGLE-CHIP.
