ADS8329IRSAR

Analog To Digital Converters (ADC) Overview

The ADS8329IRSAR 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 unipolar input configuration and supports a sampling rate of 1 MHz. The device operates with an analog supply voltage of 5V and a digital supply range of 1.65V to 5.5V. It utilizes a serial peripheral interface (SPI) for data communication. The component is housed in a 16-VQFN package with dimensions of 4x4 mm and includes a bare pad for thermal dissipation. It is rated for operation within a temperature range of -40°C to +85°C.
