ADS8904BRGER

Analog To Digital Converters (ADC) Overview

The ADS8904BRGER is a single-channel, 20-bit Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Texas Instruments. It operates with a sampling rate of 250 kSPS and supports differential input signals. The device utilizes an SPI interface for data communication and requires external reference voltage. It 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. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 104.5 dB and a gain error of 0.005% FSR. The component is housed in a 24-VQFN package and supports operation temperatures from -40°C to +125°C.
