ADS8422IBPFBR

Analog To Digital Converters (ADC) Overview

The ADS8422IBPFBR is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports a maximum sampling rate of 4 MSPS with a single-channel input configuration. The device operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 2.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 86 dB, differential nonlinearity of -1/1.5 LSB, and integral nonlinearity of +/- 2 LSB. It features a parallel interface and is housed in a TQFP-48 package.
