ADS8472IBRGZR

Analog To Digital Converters (ADC) Overview

The ADS8472IBRGZR is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential or pseudo-differential input channel and operates at a sampling rate of 1 MSPS. The device utilizes a parallel interface for data output and includes an internal oscillator. Power requirements consist of a 4.75 V to 5.25 V analog supply and a 2.7 V to 5.25 V digital supply, with typical power consumption of 225 mW. Key performance metrics include a signal-to-noise ratio of 95.3 dB, maximum INL of 0.65 LSB, and DNL of ±0.5 LSB. It is housed in a 48-VQFN package and supports external or internal reference configurations.
