ADS7951SRGET

Analog To Digital Converters (ADC) Overview

The ADS7951SRGET is a Texas Instruments microPOWER SAR ADC featuring 12-bit resolution and an 8-channel single-ended input multiplexer. It operates at a sampling rate of 1 MSPS with an external reference configuration. The device supports analog supply voltages from 2.7 V to 5.25 V and digital supplies from 1.7 V to 5.25 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 68 dB and a power consumption of 11.5 mW. It utilizes a standard SPI interface for data communication and is housed in a 24-VQFN package rated for operation between -40°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with a sample-and-hold circuit preceding the 12-bit SAR converter.
• Supports flexible power supply configurations allowing independent analog and digital voltage domains.
• Provides low-power operation suitable for battery-powered applications through optimized SAR architecture.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring multi-channel signal acquisition
• Industrial process control systems with sensor arrays
• Data acquisition modules for environmental monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GET' corresponds to the tape and reel packaging format as indicated by distributor listings. Confirm that the external reference requirement aligns with system design constraints, as internal references are not included in this variant. Ensure compatibility with the 24-VQFN footprint during PCB layout planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended channels require simultaneous or sequential conversion at high speeds up to 1 MSPS. Compare against ADS7950 variants if fewer channels are needed or ADS7953 models if higher channel counts are required. Verify that the 12-bit resolution meets the dynamic range requirements of the target application signals.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x family of microPOWER analog-to-digital converters. It shares architectural similarities with the ADS7950 and ADS7953 but is distinguished by its specific 8-channel configuration and 12-bit resolution. The SRGET suffix denotes the surface-mount QFN package with reel packaging for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7951SRGER is a compatible alternative offering identical electrical specifications but packaged in a leaded TSSOP format instead of the VQFN. Designers must account for differences in thermal dissipation and board space when substituting between these package types.
