ADS8900BRGER

Analog To Digital Converters (ADC) Overview

The ADS8900BRGER is a single-channel, 20-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a maximum sampling rate of 1 MSPS and features a differential analog input architecture. The device utilizes an SPI-compatible digital interface for data communication. Power requirements include an analog supply voltage range of 3 V to 5.5 V and a digital supply voltage range of 1.65 V to 5.5 V. It is housed in a 24-lead VQFN package with a 4 mm x 4 mm footprint. The component supports an external reference voltage between 2.5 V and 5 V and functions within a temperature range of -40°C to +125°C.
