ADS7950SBRGET

Analog To Digital Converters (ADC) Overview

The ADS7950SBRGET is a Texas Instruments microPOWER analog-to-digital converter featuring a 12-bit resolution and four single-ended input channels. It operates with a sampling rate of 1 MSPS using successive approximation register (SAR) architecture. The device 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. It utilizes an external reference voltage, typically 2.5 V, and communicates via an SPI interface. Key performance metrics include a signal-to-noise ratio (SNR) of 70 dB and a power consumption of 11.5 mW. The component is housed in a 24-VQFN package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Four-channel multiplexed input structure supporting single-ended signals for simultaneous data acquisition across multiple points.
• Low-power SAR architecture designed for battery-operated applications with minimal energy consumption during conversion cycles.
• Flexible supply voltage compatibility allowing operation with both 3.3 V and 5 V logic systems through separate analog and digital supplies.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-point sensor monitoring
• Portable instrumentation devices needing low power consumption
• Data acquisition modules for environmental sensing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GET' indicates the tape and reel packaging format when ordering. Confirm that the external reference voltage requirements align with the system design, as the device does not include an internal reference. Ensure the PCB layout accounts for the thermal pad on the VQFN package to maintain specified performance levels under continuous operation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four single-ended channels are required at 1 MSPS with 12-bit precision. Compare against the ADS7950SBDBT if a TSSOP-30 package is preferred over the VQFN form factor. Consider the ADS7951 series if eight channels are needed instead of four, while maintaining similar speed and resolution characteristics.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments microPOWER ADC family, which emphasizes low power consumption alongside moderate speed. The ADS7950 variant specifically targets applications requiring four channels, distinguishing it from the two-channel ADS794x series and the eight-channel ADS7951 series. All members share common architectural features such as the SAR core and SPI interface.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7950SDBT serves as a pin-compatible alternative offering the same electrical specifications but packaged in a TSSOP-30 footprint instead of the VQFN-24. Designers must verify board space constraints before substituting between these package types.
