ADS8322Y/250

Analog To Digital Converters (ADC) Overview

The ADS8322Y/250 is a 16-bit successive-approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input configuration and operates with a sampling rate of 500 kSPS. The device utilizes a parallel interface for data output and includes an internal reference voltage source. It requires both analog and digital supply voltages within the range of 4.75 V to 5.25 V. The component is housed in a TQFP-32 package and supports surface-mount installation. It functions reliably across an operating temperature range from -40°C to +85°C, consuming 85 mW of power under typical conditions.
