ADS7952SDBTR

Analog To Digital Converters (ADC) Overview

The ADS7952SDBTR is a 12-bit, 1-MSPS, 16-channel, single-ended, microPower successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with 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. The device features a serial interface compatible with standard SPI protocols. Key performance metrics include a signal-to-noise ratio (SNR) of 70 dB, differential nonlinearity (DNL) of +/- 1 LSB, and integral nonlinearity (INL) of +/- 1 LSB. 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 38-pin TSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SDBTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the ordering part number matches the exact pin count and package dimensions specified in the manufacturer's datasheet to ensure compatibility with existing PCB footprints. Check for RoHS compliance status if environmental regulations apply to the final product deployment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high channel count is required without sacrificing sampling speed or resolution. Compare against the ADS7950 (4-channel) and ADS7951 (8-channel) variants if fewer inputs are sufficient for the design. Ensure the system architecture supports the necessary external reference voltage and that the available supply rails align with the specified analog and digital voltage ranges.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS79xx family of microPower SAR ADCs from Texas Instruments. The family includes pin-compatible variants such as the ADS7950, ADS7951, and ADS7953, which offer different channel counts ranging from 4 to 16. This specific model represents the 16-channel configuration within the series, sharing common architectural features and interface protocols with its siblings.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS7950SDBTR (4-channel), ADS7951SDBTR (8-channel), and ADS7953SDBTR (16-channel). These parts share identical pinouts and software interfaces, allowing for straightforward upgrades or downgrades based on channel requirements.
