ADS9224RIRHBT

Analog To Digital Converters (ADC) Overview

The ADS9224RIRHBT is a dual-channel, simultaneous-sampling Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It features 16-bit resolution with no missing codes and operates at a maximum sampling rate of 3 MSPS per channel. The device supports full-differential single-polarity analog inputs and includes an integrated 2.5 V reference voltage source with a buffer. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 94 dB, Total Harmonic Distortion (THD) of -109 dB, and a Full Power Bandwidth (FPBW) of 52 MHz. It utilizes an enhanced SPI interface compatible with standard microcontrollers and FPGAs, housed in a 32-pin VQFN package.
