ADS8331IRGET

Analog To Digital Converters (ADC) Overview

The ADS8331IRGET is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an integrated multiplexer and sample-and-hold circuit for eight single-ended or pseudo-differential inputs. The device operates with an analog supply voltage range of 2.7V to 3.6V and a digital supply voltage range of 1.65V to 5.5V. It supports a maximum sampling rate of 500k samples per second. The component utilizes a serial peripheral interface (SPI) for data communication and is housed in a 24-VQFN package measuring 4x4 mm. It is rated for operation within a temperature range of -40°C to 85°C.
