DDC112Y/250 TI Dual Current Input ADC | 32-TQFP (7x7) | 20-bit, 2-Channel

Product Overview

The DDC112Y/250 is a precision dual current input analog-to-digital converter (ADC) from Texas Instruments. It integrates two integrating ADCs with a 20-bit resolution, designed for high-accuracy current measurement applications. The device operates from a single +5V supply and features a maximum conversion rate of 250 samples per second per channel. It is housed in a compact 32-pin TQFP package (7x7 mm), making it suitable for space-constrained designs.
