ADS7956QDBTRQ1

Analog To Digital Converters (ADC) Overview

The ADS7956QDBTRQ1 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed for automotive applications. 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 supports a maximum sampling rate of 1 MSPS and features a serial peripheral interface (SPI) compatible with standard modes. It is housed in a TSSOP-38 package and is qualified under the AEC-Q100 standard. The component functions within a temperature range from -40°C to +125°C and consumes approximately 14.5 mW of power.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration and tape-and-reel specifications. Confirm that the AEC-Q100 qualification status aligns with your project's automotive reliability requirements. Check for moisture sensitivity level markings on the reel label to determine baking procedures before assembly. Ensure the supplier provides valid traceability documentation for automotive grade components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. Consider the TSSOP-38 package dimensions for PCB layout constraints. Evaluate the power consumption against thermal management capabilities in enclosed automotive enclosures. Verify compatibility with the system's SPI clock speeds and voltage levels for reliable communication.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7956 family of micro-power ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7950 and ADS7953 but differs in channel count and package options. The 'Q' suffix indicates automotive qualification, while 'DBTR' specifies the TSSOP-38 reel packaging. It serves as a specialized solution for automotive data acquisition where space and power are critical.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other AEC-Q100 qualified single-channel 12-bit SAR ADCs from Texas Instruments. Verify pinout compatibility and software register settings if migrating between different series members. Cross-reference package dimensions to ensure mechanical fit without PCB redesign.
