ADS7950SBRGER

Analog To Digital Converters (ADC) Overview

The ADS7950SBRGER is a micro power, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It features four single-ended input channels and operates at a sampling rate of 1 MSPS. The device utilizes a successive approximation register (SAR) architecture and communicates via an SPI-compatible serial 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. Key performance metrics include a signal-to-noise ratio (SNR) of 70 dB and a signal-to-noise and distortion ratio (SINAD) of 71.3 dB. The component is housed in a 24-VQFN package with dimensions of 4 mm by 4 mm.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a multiplexer, sample-and-hold amplifier, and 12-bit SAR ADC for efficient data acquisition.
• Designed for low-power applications with a typical power consumption of 11.5 mW.
• Features flexible power supply options allowing independent analog and digital domain voltages.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring high accuracy and low power.
• Industrial process control and monitoring applications.
• Medical equipment and battery-powered sensing devices.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GER' against the manufacturer's official documentation to confirm it denotes the tape and reel packaging variant rather than a functional difference. Ensure compatibility with standard SPI protocols and check for any specific moisture sensitivity level requirements during storage and handling.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate channel count and high speed is required. Compare against the ADS7951 for eight-channel needs or the ADS7950SBDBT for TSSOP-30 packaging alternatives. Confirm that the external reference voltage requirement aligns with system design constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x family of micro power ADCs. It shares architectural similarities with the ADS7951 and ADS7953 but differs in channel count and package type. The series is designed for applications demanding low power consumption without sacrificing resolution or sampling speed.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7950SBDBTR: Same electrical specifications but in a TSSOP-30 package. ADS7951SBRGET: Offers eight channels instead of four with identical performance characteristics. ADS7953SBRHBT: Provides sixteen channels in a larger VQFN-32 package.
