ADS9224RIRHBR

Analog To Digital Converters (ADC) Overview

The ADS9224RIRHBR 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 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 of 52 MHz. It utilizes an enhanced SPI interface compatible with microcontrollers and FPGAs, housed in a 5 mm x 5 mm VQFN-32 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including suffixes such as IRHBR to ensure correct packaging and temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure supply chain sources are authorized distributors to guarantee authenticity and traceability of the semiconductor components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous dual-channel sampling at 16-bit resolution is required. Consider the 52 MHz input bandwidth and 3 MSPS speed for wideband signal processing. Evaluate the integrated reference against external precision references if lower noise or different voltage levels are needed. Check interface compatibility with the target MCU or FPGA regarding SPI mode support.
