ADS7043IRUGR

Analog To Digital Converters (ADC) Overview

The ADS7043IRUGR 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 a digital supply voltage of the same range. The device achieves a sampling rate of 1 MSPS with pseudo-differential input configuration. It features an SPI-compatible serial interface for data output. The component is housed in an 8-X2QFN package measuring 1.5mm x 1.5mm. It is rated for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Ultra-low power consumption of 243 µW at maximum sampling rate
• Compact 8-X2QFN package size of 1.5mm x 1.5mm for space-constrained designs
• Integrated sample-and-hold amplifier with 1:1 ratio to ADC core
• Single-supply operation compatible with low-voltage digital systems

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation
• Industrial process control sensors
• Medical monitoring devices
• Data acquisition systems requiring small form factor

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRUGR corresponds to the industrial temperature grade (-40°C to +125°C) and the 8-X2QFN package variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure ordering quantities match the standard reel or cut tape availability specified by the distributor. Cross-reference the datasheet revision date to ensure all electrical characteristics align with current production standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate resolution (12-bit) and high speed (1 MSPS) is required in a minimal footprint. It is suitable for applications where power efficiency is critical but does not demand the highest precision of higher-bit SAR ADCs. Compare against the ADS7044 if differential inputs are preferred over pseudo-differential configurations. Consider the ADS7043IDCUT alternative if VSSOP-8 packaging is required instead of QFN.

Analog To Digital Converters (ADC) Part Context

The ADS7043 belongs to the ADS704x family of ultra-low-power SAR ADCs from Texas Instruments. This series includes variants such as the ADS7041, ADS7043, and ADS7044, which share similar architectural features but differ in resolution, input types, and package options. The ADS7043 specifically targets cost-sensitive, space-limited applications requiring single-channel conversion capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7043IDCUT offers the same electrical specifications but utilizes a VSSOP-8 package instead of the X2QFN format. ADS7044 provides differential input capability while maintaining similar performance metrics. Verify pinout compatibility and thermal dissipation requirements when substituting packages.
