ADS5281IRGCT

Analog To Digital Converters (ADC) Overview

The ADS5281IRGCT is an ultra-low-power, eight-channel analog-to-digital converter manufactured by Texas Instruments. It features a pipeline architecture with 12-bit resolution and operates at sampling rates up to 65 MS/s per channel. The device consumes approximately 64 mW of power per channel, totaling around 512 mW for the full array. It utilizes serialized DDR LVDS outputs to minimize trace counts and FPGA pin consumption. Power supplies include 3V to 3.6V for analog and 1.7V to 1.9V for digital sections. The component is housed in a compact 64-VQFN (9x9mm) package with exposed pads, supporting differential inputs and synchronous sampling capabilities.
