ADS7044IRUGR

Analog To Digital Converters (ADC) Overview

The ADS7044IRUGR is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single fully differential input and operates with an analog supply voltage range of 1.65V to 3.6V and a digital supply voltage range of 1.65V to 3.6V. The device supports a sampling rate of 1MSPS and communicates via an SPI interface. It is housed in an 8-X2QFN package measuring 1.5x1.5 mm, suitable for surface mount installation. The component functions within a temperature range of -40°C to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRUGR corresponds to the 8-X2QFN(1.5x1.5) package and industrial temperature grade. Confirm the datasheet revision matches the required specifications. Ensure the ordering quantity aligns with standard reel sizes if applicable. Check for RoHS compliance status as indicated in official documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 1MSPS speed are sufficient for the application. Consider the fully differential input requirement versus single-ended alternatives. Evaluate the 1.65V to 3.6V supply range compatibility with system power rails. Compare the 8-X2QFN footprint against available PCB space constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7044 family of ultra-low-power SAR ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7042 and ADS7046, differing primarily in resolution and speed. The IRUGR designation specifies the industrial temperature range and the specific QFN package variant within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7044IDCUR is a pin-compatible alternative in an 8-VSSOP package. ADS7042IRUGR offers lower resolution but similar power characteristics. ADS7046IRUGR provides higher speed options within the same package.
