DDC112UK TI Dual Current Input ADC | 28-SOIC | 20-bit, 2-Channel

Product Overview

The DDC112UK is a precision dual-channel current-input analog-to-digital converter (ADC) from Texas Instruments. It integrates two integrating converters with 20-bit resolution, designed for high-accuracy measurement of low-level currents. Housed in a 28-pin SOIC package, it operates from a single +5V supply and features a serial interface for data output. The device is ideal for applications requiring simultaneous sampling of two current signals, such as photodiode sensors, X-ray detectors, and medical imaging equipment.
