ADS7951QDBTRQ1

Analog To Digital Converters (ADC) Overview

The ADS7951QDBTRQ1 is a single-ended, low-power analog-to-digital converter (ADC) from Texas Instruments. It features a 12-bit resolution and operates at a sampling rate of 1 MSPS. The device utilizes a successive approximation register (SAR) architecture with an internal sample-and-hold circuit. It supports a wide 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 component is housed in a TSSOP-38 package and is qualified under AEC-Q100 standards for automotive applications. Typical power consumption is 14.5 mW at 1 MSPS.

Analog To Digital Converters (ADC) Feature Summary

• AEC-Q100 qualified for automotive environments with specified temperature ranges
• Low power consumption suitable for battery-operated systems
• Configurable GPIO pins for flexible system integration

Analog To Digital Converters (ADC) Applications

• Automotive sensor monitoring
• Industrial data acquisition systems
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q100 qualification level matches the target application requirements. Check for moisture sensitivity levels and recommended reflow soldering profiles prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit ADC with high speed and low power is required. Ensure the input signal range aligns with the available reference voltage options. Verify that the TSSOP-38 footprint fits the PCB layout constraints compared to other channel counts in the series.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS79xx-Q1 family of multi-channel SAR ADCs designed for automotive use. While sharing architectural similarities with higher-channel variants like the ADS7956QDBTRQ1, it is specifically configured as a single-channel device. This distinction reduces pin count and simplifies interface requirements for point-of-use sensing applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS7953QDBTRQ1 or ADS7959QDBTRQ1 if additional channels are acceptable. Verify pin compatibility and software register mapping before swapping to different channel counts in the ADS79xx-Q1 series.
