ADS7046IRUGR

Analog To Digital Converters (ADC) Overview

The ADS7046IRUGR is a 12-bit Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Texas Instruments. It features a single-ended input architecture and supports a sampling rate of 3 MSPS. The device operates with an analog supply voltage range of 2.7 V to 5.5 V and a digital supply voltage range of 1.65 V to 3.6 V. It utilizes a serial Peripheral Interface (SPI) for data communication. The component is housed in an 8-X2QFN package measuring 1.5 mm by 1.5 mm, suitable for surface-mount installation. It functions within a temperature range of -40°C to 125°C.

Analog To Digital Converters (ADC) Feature Summary

• Ultra-small size packaging facilitates dense circuit board layouts
• Low power consumption optimized for battery-operated applications
• Single-ended input configuration simplifies signal conditioning

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Battery-powered sensor interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRUGR' corresponds to the tape-and-reel packaging variant and industrial temperature grade. Confirm that the single-ended input requirement matches the system design, as differential variants exist within the same family. Ensure compatibility with the required SPI clock speeds and voltage levels before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution at 3 MSPS is required with minimal footprint constraints. Compare against ADS7044 if differential inputs are needed instead of single-ended. Verify that the 2.7 V minimum analog supply meets the system's lowest operating voltage conditions. Consider the ADS7042 or ADS7043 if lower sampling rates or different input types better suit the application.

Analog To Digital Converters (ADC) Part Context

The ADS7046 belongs to the ADS704x family of ultra-low-power SAR ADCs from Texas Instruments. This series shares common architectural features such as the small X2QFN package and low power profiles. The ADS7046 specifically distinguishes itself through its 3 MSPS speed and single-ended input capability, differentiating it from the slower ADS7040/ADS7042 or the differential ADS7044.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7044IRUGR offers similar performance but with differential inputs. ADS7042IRUGR provides 1 MSPS sampling with single-ended inputs. ADS7046IDCUR is the VSSOP-8 package equivalent.
