ADS7952SBDBTG4

Analog To Digital Converters (ADC) Overview

The ADS7952SBDBTG4 is a 12-bit, 1-MSPS, 12-channel single-ended microPower successive approximation register (SAR) analog-to-digital converter (ADC). 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. It achieves a signal-to-noise ratio (SNR) of 60 dB and maintains differential nonlinearity (DNL) and integral nonlinearity (INL) within +/- 0.5 LSB. The component is housed in a 38-pin TSSOP package and supports an operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates 12 single-ended input channels for multi-point sensing applications
• Delivers high-speed conversion at 1 MSPS with low power consumption characteristics
• Supports flexible logic levels through independent analog and digital supply domains

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable instrumentation benefiting from low-power operation
• Automotive sensor interfaces operating across extended temperature ranges

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the specific tape-and-reel or tube packaging variant matches the assembly requirements. Ensure the ordering part number aligns exactly with the required pin count and package dimensions for PCB footprint compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 12 single-ended channels are required alongside 12-bit resolution and 1 MSPS throughput. Compare against ADS7950 variants if fewer channels suffice, or ADS7953 models for increased channel counts. Verify that the external reference voltage capability meets system accuracy needs given the +/- 0.5 LSB linearity specifications.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS795x family of microPower SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7950, ADS7951, ADS7953, and ADS7954 models, differing primarily in channel count and package options. The family targets applications demanding moderate speed and resolution with minimal power usage.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7952SBDBT serves as the non-RoHS equivalent. ADS7952SBDBTR offers reel packaging instead of tube. ADS7953SBDBTG4 provides 16 channels instead of 12. ADS7950SBDBTG4 provides 4 channels instead of 12.
