ADS9234RIRHBR

Analog To Digital Converters (ADC) Overview

The ADS9234RIRHBR is a dual-channel, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It features simultaneous sampling with a data rate of 3 MSPS per channel and utilizes a Successive Approximation Register (SAR) architecture. The device operates with a 5 V analog supply and a 3.3 V digital supply, housed in a 32-pin VQFN package. Key performance metrics include a signal-to-noise ratio (SNR) of 94 dB, an effective number of bits (ENOB) of 15.8 bits, and a full-power bandwidth of 52 MHz. It supports differential inputs and offers enhanced SPI compatibility for digital interfacing.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RHB' to confirm the reel packaging configuration and tape-and-reel quantity. Ensure the component matches the VQFN-32 footprint dimensions during PCB layout review. Confirm RoHS compliance status through the manufacturer's official documentation before integration into regulated assemblies.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required at 16-bit resolution. Compare SNR and ENOB specifications against system noise floors. Verify that the 52 MHz full-power bandwidth meets the input signal frequency requirements. Ensure the host microcontroller supports the enhanced SPI timing constraints defined in the datasheet.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS9224R family of dual-channel ADCs. It shares architectural similarities with other members but is distinguished by its specific pinout, packaging, and electrical characteristics. The family targets applications demanding high accuracy and low power consumption in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify if single-channel variants can be paired if dual-channel operation is not strictly necessary. Ensure substitute parts maintain compatible supply voltages and SPI interface protocols.
