DDC112U TI Dual Current Input ADC | 28-SOIC | 20-bit, 2-Channel

Product Overview

The DDC112U is a precision, dual-channel, current-input analog-to-digital converter (ADC) from Texas Instruments. It is designed for direct connection to photodiodes and other low-level current sources, integrating two integrators, a multiplexer, and a 20-bit delta-sigma ADC in a single 28-SOIC package. The device provides high accuracy, low noise, and excellent linearity, making it ideal for applications requiring precise current measurement.
