ADS9226IRHBT

Analog To Digital Converters (ADC) Overview

The ADS9226IRHBT is a dual-channel, simultaneous-sampling analog-to-digital converter with 16-bit resolution and a throughput of 2.048 MSPS. It features a low latency of 488 ns and operates on a single 5-V analog supply (4 V to 5.5 V) with a 3.3-V digital interface. The device supports unipolar, pseudo-differential inputs and includes integrated reference buffers. Key performance metrics include a signal-to-noise ratio of 90.8 dB, total harmonic distortion of -100 dB, and a full-power bandwidth of 52 MHz. It utilizes an enhanced SPI-compatible serial interface and is housed in a 5-mm × 5-mm VQFN-32 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'IRHBT' against the manufacturer's current orderable addendum to confirm the tape-and-reel packaging configuration. Ensure that the component meets RoHS compliance requirements for the intended deployment environment. Cross-reference the datasheet revision history to validate that all electrical specifications align with the production batch being procured.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous dual-channel acquisition is required at 16-bit resolution. The integrated reference buffers reduce the need for external precision voltage references. Verify that the system clock frequency supports the maximum 2.048 MSPS sampling rate through the SPI interface. Confirm that the input signal range matches the pseudo-differential specification relative to the chosen reference voltage.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS9226 family of high-speed SAR ADCs from Texas Instruments. It is designed for applications requiring precise, synchronized data acquisition across multiple channels.
