ADS7223SRHBR

Analog To Digital Converters (ADC) Overview

The ADS7223SRHBR is a dual-channel, simultaneous-sampling successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a 12-bit resolution and supports sampling rates up to 1 MSPS per channel. The device integrates two independently controlled internal voltage references, simplifying system design. It accepts differential or pseudo-differential inputs through an integrated multiplexer and sample-and-hold circuit. Power consumption is rated at 47.2 mW. The component operates with analog supply voltages ranging from 2.7 V to 5.5 V and digital supply voltages from 2.3 V to 5.5 V. It utilizes a serial interface for data output and is housed in a 32-VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix SRHBR corresponds to the reel packaging format when ordering. Confirm that the 12-bit resolution variant matches the application requirements, as the ADS7223 family includes higher resolution options. Ensure compatibility with the required serial interface timing specifications during integration. Check moisture sensitivity level handling procedures for the VQFN package prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is critical for phase-sensitive applications. The integrated references reduce external component count compared to devices requiring external voltage references. Consider the 1 MSPS throughput limit against the Nyquist rate of the input signals. Evaluate the 32-VQFN package size constraints against available PCB real estate.

Analog To Digital Converters (ADC) Part Context

The ADS7223SRHBR belongs to the ADSxxx3 family of dual-channel ADCs, which also includes the 14-bit ADS7263 and 16-bit ADS8363. These parts share pin-for-pin compatibility and similar functional blocks, differing primarily in resolution and noise performance. This family targets high-throughput industrial applications where channel synchronization is essential.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7263SRHBR and ADS8363SRHBR are pin-compatible alternatives offering 14-bit and 16-bit resolutions respectively. Verify if the increased resolution justifies potential changes in power consumption or cost. Other family members may require software adjustments due to different data formats or timing characteristics.
