ADS8914BRGER

Analog To Digital Converters (ADC) Overview

The ADS8914BRGER is a single-channel, 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 250 kSPS and features a differential input architecture. The device utilizes an external reference voltage ranging from 2.5 V to the analog supply voltage. It supports SPI digital interfaces and includes daisy-chainable capabilities with an internal oscillator. Power consumption is specified at 14 mW. The component functions within an analog supply range of 3 V to 5.5 V and a digital supply range of 1.65 V to 5.5 V. It is housed in a 24-pin VQFN package and operates across a temperature range of -40°C to +125°C.
