ADS7951SDBT

Analog To Digital Converters (ADC) Overview

The ADS7951SDBT is a 12-bit, 1-MSPS, 8-channel, single-ended microPower successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an external reference input and 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 device utilizes a serial peripheral interface (SPI) for data communication. It is housed in a 30-pin Thin-Shrink Small Outline Package (TSSOP). The ADC supports a sampling rate of 1 MSPS across its eight channels, with a typical power consumption of 11.5 mW. The operational temperature range extends from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with a sample-and-hold amplifier for efficient multi-point acquisition.
• Supports flexible system integration through an external reference voltage input option.
• Enables low-power operation suitable for battery-driven applications via microPower 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 package variant and suffix against official Texas Instruments documentation to ensure compatibility with design requirements. Confirm that the external reference configuration matches the intended application voltage levels. Check for moisture sensitivity level compliance during storage and handling procedures.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended inputs are required at 12-bit resolution and 1 MSPS throughput. Compare against the ADS7950 for four-channel needs or the ADS7953 for sixteen-channel configurations within the same family. Ensure the TSSOP-30 footprint aligns with the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x series of microPower SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7950, ADS7953, and ADS7955, differing primarily in channel count and package options. The series is designed for general-purpose data acquisition tasks requiring moderate speed and resolution.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7951SBDBTR offers the same electrical specifications in a tape-and-reel packaging format for automated assembly. ADS7951SBRGET provides identical performance in a 24-VQFN package for space-constrained designs.
