ADS7952SRHBR

Analog To Digital Converters (ADC) Overview

The ADS7952SRHBR is a 12-bit, 16-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features a single-ended input architecture and operates with an SPI-compatible serial interface. The device supports a sampling rate of 1 MSPS and functions within 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 an integral nonlinearity (INL) of 0.048% FSR. It consumes 11.5 mW of power and is housed in a VQFN-32 package, operating reliably between -40°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• High-density multiplexing capability with 16 single-ended channels integrated into a compact VQFN-32 package.
• Low-power SAR architecture designed for micro-power applications with external reference support.
• Flexible dual-supply operation allowing independent optimization of analog and digital logic levels.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition.
• Portable instrumentation utilizing battery-powered single-ended sensor inputs.
• Automotive monitoring circuits operating across extended temperature ranges.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BR' indicates the reel packaging format when sourcing. Confirm that the VQFN-32 package requires appropriate thermal management considerations during PCB layout. Ensure the external reference voltage matches the required input range for optimal SNR performance. Check humidity sensitivity levels for storage and reflow soldering compliance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 12-bit resolution and 16 channels are required in a small footprint. Compare against the ADS7953 if higher 12-bit accuracy is needed, or the ADS7957 for 10-bit resolution with similar channel counts. Consider the ADS7960 if only 8-bit resolution and 12 channels suffice for cost reduction. Verify SPI compatibility with the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x family of micro-power SAR ADCs from Texas Instruments. It shares the same VQFN-32 package and core architecture as the ADS7953, ADS7957, and ADS7960. The primary differentiator is its combination of 12-bit resolution and 16 channels, filling a niche between the lower-resolution ADS7960 and the higher-accuracy ADS7953.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7953SBDBT: Offers identical 12-bit/16-channel specs but in a TSSOP package. ADS7957SRHBR: Provides 10-bit resolution and 16 channels in the same VQFN-32 package. ADS7960SRHBR: Provides 8-bit resolution and 12 channels in the same VQFN-32 package.
