ADS7223SRHBT

Analog To Digital Converters (ADC) Overview

The ADS7223SRHBT 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 and accepts differential or pseudo-differential inputs. It operates with an analog supply voltage range of 2.7V to 5.5V and a digital supply voltage range of 2.3V to 5.5V. The component utilizes a serial SPI interface for data output and is housed in a 32-pin VQFN package measuring 5mm x 5mm.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling capability across two channels ensures precise phase alignment for multi-phase applications.
• Integrated dual independent internal voltage references simplify system-level design by reducing external component count.
• High throughput performance allows operation at speeds up to 1 MSPS, supporting demanding industrial signal processing tasks.

Analog To Digital Converters (ADC) Applications

• Motor control systems requiring synchronized current and voltage feedback
• Power quality measurement equipment for grid monitoring
• Protection relays in electrical distribution networks

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix SRHBT against the manufacturer's datasheet to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with the target PCB footprint for the 32-VQFN package. Confirm that the operating temperature range meets the environmental requirements of the final assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required rather than sequential multiplexing. Compare the 12-bit resolution against higher-resolution alternatives like the ADS8363 if greater precision is needed. Verify that the SPI interface timing matches the host microcontroller capabilities and that the power supply rails align with the specified analog and digital voltage ranges.

Analog To Digital Converters (ADC) Part Context

The ADS7223 belongs to a family of pin-for-pin compatible devices that includes the 14-bit ADS7263 and the 16-bit ADS8363. This series shares the same 32-VQFN package and functional architecture, differing primarily in resolution. The ADS7223 serves as the entry-level option within this high-speed simultaneous sampling lineup.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7263SRHBT and ADS8363SRHBT are pin-compatible upgrades offering higher resolutions of 14 bits and 16 bits respectively. These substitutes maintain the same package and interface but provide increased dynamic range without requiring PCB layout changes.
