ADS7952SBRHBT

Analog To Digital Converters (ADC) Overview

The ADS7952SBRHBT is a 12-bit, 1-MSPS, 12-channel single-ended microPower SAR ADC manufactured by Texas Instruments. It features an SPI-compatible serial interface and operates with analog supply voltages from 2.7 V to 5.25 V and digital supplies from 1.7 V to 5.25 V. The device achieves a signal-to-noise ratio (SNR) of 71.7 dB and a SINAD of 71.3 dB, with integral nonlinearity (INL) specified at 0.024% FSR. It consumes 11.5 mW of power and functions within a temperature range of -40°C to +125°C. The component is housed in a 32-pin VQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Supports flexible power supply configurations for mixed-voltage systems

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 'RHBT' against the manufacturer's official datasheet to confirm the reel packaging configuration and moisture sensitivity level. Ensure the ordering part number matches the exact pinout and thermal pad requirements for the VQFN-32 package before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and high channel count is required for single-ended inputs. Compare SNR and INL specifications against system noise floors. Verify that the external reference voltage capability aligns with the application's accuracy requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS79xx family of single-ended, microPower SAR ADCs. It shares architectural similarities with the ADS7950 and ADS7953 models, differing primarily in channel count and package options. The family targets applications requiring multiple analog inputs with low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7953SBRHBT offers identical performance characteristics but provides 16 channels instead of 12. Designers may consider this alternative if additional input channels are needed without changing the footprint or power budget.
