ADS9120IRGET

Analog To Digital Converters (ADC) Overview

The ADS9120IRGET is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports a maximum sampling rate of 2.5 MSPS with a typical power consumption of 9 mW at full speed. The device features an SPI-compatible digital interface and operates on a single analog supply voltage ranging from 2.7 V to 5.5 V, alongside a digital supply range of 1.65 V to 5.5 V. It is housed in a 24-pin VQFN package with dimensions of 4 mm x 4 mm. The input range is defined by the reference voltage, and it includes internal daisy-chain capabilities for multi-device systems.
