ADS8422IPFBR

Analog To Digital Converters (ADC) Overview

The ADS8422IPFBR is a high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with an integrated reference and operates on a single 5V analog supply alongside a 2.7V to 5.25V digital supply. The device delivers a maximum sampling rate of 3MSPS with a conversion time of 0.28µs. It utilizes a parallel interface for data output and is housed in a 48-lead Thin Quad Flatpack (TQFP) package. The component supports an analog input voltage range up to 2.6V and functions within an industrial temperature range of -40°C to +85°C.
