ADS7957SRHBR

Analog To Digital Converters (ADC) Overview

The ADS7957SRHBR is a 10-bit, 16-channel single-ended successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a maximum sampling rate of 1 MSPS and features an SPI-compatible serial interface. The device requires an external voltage reference and supports analog supply voltages from 2.7 V to 5.25 V and digital supply voltages from 1.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 60 dB, integral nonlinearity (INL) of 0.048% FSR, and power consumption of 11.5 mW. It is housed in a 32-pin VQFN package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Provides high channel density with 16 single-ended inputs for compact multi-point sensing applications.
• Delivers low power consumption of 11.5 mW suitable for battery-operated or energy-constrained systems.
• Features flexible supply voltage ranges allowing compatibility with various system logic levels.

Analog To Digital Converters (ADC) Applications

• Industrial process control monitoring
• Portable data acquisition systems
• Battery-powered instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BR' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the external voltage reference meets the required accuracy specifications to maintain the ADC's linearity performance. Check humidity sensitivity levels for proper storage and handling procedures during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and high channel count is required. Compare against the ADS7953 for higher 12-bit resolution or the ADS7960 for lower 8-bit resolution options within the same family. Consider the VQFN-32 package constraints for PCB layout. Evaluate the need for single-ended versus differential input requirements relative to other family members.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x series of micro-power SAR ADCs from Texas Instruments. The series shares common architectural features including a 1 MSPS sampling rate and SPI interface. Variants differ primarily in resolution (8-bit, 10-bit, 12-bit) and channel count (4, 8, 12, 16). The SRHBR designation specifies the 10-bit, 16-channel configuration in a VQFN package.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7953SRHBR offers 12-bit resolution with identical channel count and package. ADS7960SRHBR provides 8-bit resolution with 12 channels. ADS7957SDBTRG4 is a tube-packaged alternative with the same electrical characteristics.
