ADS7954QDBTRQ1

Analog To Digital Converters (ADC) Overview

The ADS7954QDBTRQ1 is a single-channel, 10-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 I/O supply 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). It is housed in a TSSOP-30 package and is qualified under AEC-Q100 standards for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• AEC-Q100 qualified for automotive reliability

• Single-ended input configuration with external reference support

Analog To Digital Converters (ADC) Applications

• Automotive sensor monitoring
• Battery management systems
• Industrial data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix Q1 confirms AEC-Q100 automotive qualification status. Confirm the TSSOP-30 package type matches the design footprint requirements. Ensure the external reference voltage aligns with the specified operating range for optimal performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 10-bit resolution is required for automotive environments. Compare against other ADS79xx-Q1 variants if multiple channels or different resolutions are needed. Verify SPI compatibility with the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS79xx-Q1 family of low-power, high-speed SAR ADCs. It shares architectural similarities with multi-channel variants like the ADS7953 and ADS7956 but offers a simplified single-channel configuration. The family is characterized by its ability to operate from wide supply voltages and its suitability for harsh automotive conditions.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include ADS7953QDBTRQ1 for higher channel counts or ADS7956QDBTRQ1 for increased resolution. Ensure pinout compatibility when swapping between different channel counts in the series.
