ADS9226IRHBR

Analog To Digital Converters (ADC) Overview

The ADS9226IRHBR is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 2.048 MSPS and features differential inputs. The device utilizes an internal supply-referenced voltage architecture, requiring a 5 V analog supply and a 3.3 V digital supply. Key performance metrics include a signal-to-noise ratio of 90.8 dB, a full-power bandwidth of 52 MHz, and a spurious-free dynamic range characterized by a SINAD of 90.5 dB. Linearity specifications specify a maximum DNL of 0.55 LSB and INL of 2.75 LSB. It communicates via an SPI interface and is housed in a VQFN-32 package, supporting operation from -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRHBR against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and temperature grade. Ensure the ordering part number matches the exact pinout and electrical characteristics defined in the latest TI documentation before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization at 16-bit resolution is required without external reference circuitry. Compare SNR and power consumption against similar SAR ADCs if system noise budgets are tight. Verify that the 5 V analog supply aligns with existing system power rails to minimize component count.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS9226 family of high-speed, low-power SAR ADCs. It shares architectural similarities with other members like the ADS9224 but offers specific trade-offs in sampling speed and noise performance. The VQFN-32 package is common across several Texas Instruments precision data converters.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS9224RIRHBR is a documented alternative within the same product family, offering higher sampling rates. Verify compatibility regarding pinouts and software interfaces before substitution.
