ADS7951SBRGET

Analog To Digital Converters (ADC) Overview

The ADS7951SBRGET is a microPOWER™ analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an 8-channel multiplexer with a single sample-and-hold amplifier and a successive approximation register (SAR) architecture. The device offers 12-bit resolution and supports sampling rates up to 1 MSPS. It operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.7 V to 5.25 V. The component utilizes an external reference type and communicates via an SPI interface. It is housed in a 24-VQFN package with dimensions of 4x4 mm and includes a bare pad for thermal dissipation.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel input multiplexer with a single sample-and-hold circuit to reduce power consumption compared to independent channel architectures.
• Supports flexible power management through separate analog and digital supply domains, allowing the digital interface to operate at lower voltages.
• Provides high-speed data conversion capabilities with a throughput rate of 1 MSPS while maintaining low total power dissipation.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring multi-channel signal acquisition
• Industrial process control systems with sensor inputs
• Data acquisition modules for battery-powered devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GET' corresponds to the tape and reel packaging configuration as indicated by distributor listings. Confirm that the 24-VQFN package variant matches the design footprint requirements. Ensure compatibility with the required operating temperature range of -40°C to +125°C for the intended application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel single-ended input configuration is required with 12-bit resolution. It is suitable for designs needing an external voltage reference rather than an internal one. Consider the 24-VQFN package constraints regarding thermal performance and PCB layout space when finalizing the schematic.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x series of microPOWER ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7950 and ADS7953 but is distinct in its 12-bit resolution and 8-channel count. The series is designed for applications balancing speed and power efficiency.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7951SRGER is a pin-compatible alternative in a different package. ADS7950SBDBTR offers 4 channels with 12-bit resolution. ADS7953SBDBT provides 16 channels with 12-bit resolution. Verify package and channel count differences before substitution.
