ADS7042IRUGR

Analog To Digital Converters (ADC) Overview

The ADS7042IRUGR is a single-channel, 12-bit Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 1.65V to 3.6V and supports digital supply voltages within the same 1.65V to 3.6V window. The device achieves a maximum sampling rate of 1 MSPS with a single-ended input configuration. It utilizes a standard SPI data interface for communication. The component is housed in an 8-X2QFN package measuring 1.5x1.5 mm, suitable for surface-mount installation. It functions reliably across a wide operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Ultra-small footprint utilizing an 8-X2QFN package with dimensions of 1.5x1.5 mm to minimize PCB area.
• Low power consumption architecture optimized for battery-operated applications.
• Integrated sample-and-hold circuitry with a 1:1 ratio relative to the ADC core.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring low power and small size
• Industrial process control systems with limited board space
• Battery-powered sensor nodes in IoT networks

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRUGR' corresponds to the tape and reel packaging format and the extended industrial temperature grade (-40°C to +125°C). Confirm that the order quantity aligns with the manufacturer's standard reel size specifications to ensure proper handling and storage conditions upon receipt.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input is required rather than the differential input found in the ADS7044 variant. Ensure the system design accommodates the 1.65V to 3.6V supply range. Verify that the SPI interface timing requirements are compatible with the host microcontroller or DSP used in the application design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS704x family of ultra-low-power SAR ADCs from Texas Instruments. It shares the same physical package and pinout as the ADS7044 but differs in input type, supporting single-ended signals instead of fully differential inputs. This family is designed to address space-constrained applications where power efficiency is critical.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7042IDCUT serves as a cut-tape alternative within the same series. For differential input requirements, the ADS7044IRUGR is the functional equivalent within the same package. Cross-referencing should verify that the specific suffix indicates the correct temperature grade and packaging format.
