ADS7951SDBTG4

Analog To Digital Converters (ADC) Overview

The ADS7951SDBTG4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features eight single-ended input channels and operates at a sampling rate of 1 MSPS. The device utilizes an external reference voltage and communicates via a standard SPI interface. It supports 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 is housed in a 30-TSSOP package with a wide operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Eight-channel multiplexed input architecture for single-ended signal acquisition
• Low-power SAR conversion architecture optimized for microPower applications
• Flexible dual-supply operation supporting varying logic levels

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable instrumentation powered by battery sources
• Vibration monitoring and condition-based maintenance sensors

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS conformity as per Texas Instruments standards. Confirm the TSSOP-30 package variant matches the target PCB footprint. Ensure the external reference circuitry aligns with the specified voltage requirements for optimal performance.

Analog To Digital Converters (ADC) Selection Notes

Select this model when eight single-ended inputs are required within a compact surface-mount package. Compare against the ADS7951SBRGET if a QFN footprint is preferred for space-constrained designs. Verify that the 1 MSPS throughput meets the system bandwidth requirements without necessitating higher-speed alternatives.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS795x family of microPower ADCs, which share common architectural features such as SAR topology and SPI interfaces. The ADS7951 specifically provides eight channels, distinguishing it from the four-channel ADS7950 and the sixteen-channel ADS7953 variants within the same series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7951SDBT serves as the non-green equivalent. ADS7951SBRGET offers an alternative 24-VQFN package option.
