ADS8472IBRGZT

Analog To Digital Converters (ADC) Overview

The ADS8472IBRGZT 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 supports sampling rates up to 1 MSPS. The device utilizes a parallel data interface and operates with an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply voltage between 2.7 V and 5.25 V. Key performance metrics include a signal-to-noise ratio of 95.3 dB, a maximum integral nonlinearity of 0.65 LSB, and a differential nonlinearity of ±0.5 LSB. It is housed in a 48-pin VQFN package and includes an internal oscillator.
