ADS8329IRSAT

Analog To Digital Converters (ADC) Overview

The ADS8329IRSAT is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended or pseudo-differential input architecture with an internal sample-and-hold amplifier and a precision voltage reference. The device operates from a single 5V analog supply and a digital supply ranging from 1.65V to 5.5V. It supports serial communication via a standard SPI interface and delivers a sampling rate of 1 MSPS. The component is housed in a 16-pin VQFN package with dimensions of 4mm x 4mm and is rated for operation within the industrial temperature range of -40°C to +85°C.
