ADS8472IRGZR

Analog To Digital Converters (ADC) Overview

The ADS8472IRGZR is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and features a parallel digital interface. The device supports differential or pseudo-differential input configurations and utilizes an internal or external reference voltage source. Power supply requirements include an analog voltage range of 4.75 V to 5.25 V and a digital voltage range of 2.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 95.3 dB, a maximum integral nonlinearity of ±0.65 LSB, and a differential nonlinearity of ±0.5 LSB. The component is housed in a 48-VQFN package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed SAR architecture with an internal oscillator for efficient data conversion.
• Supports flexible input configurations including differential and pseudo-differential modes.
• Offers dual reference options allowing selection between internal and external voltage references.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition.
• Medical instrumentation utilizing precision analog signal processing.
• Test and measurement equipment demanding low distortion and high linearity.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix designation carefully, as the IRGZR variant denotes a reel packaging format distinct from the RGZT cut tape option. Confirm that the procurement channel provides traceable documentation matching the manufacturer's specifications. Ensure compliance with RoHS directives and check for any moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution with 1 MSPS throughput is required. Compare against the ADS8471 if pseudo-differential inputs are sufficient, noting its lower accuracy specifications. Consider the ADS8472IBRGZT if cut tape packaging is preferred over reel formats. Evaluate power consumption constraints against the specified 225 mW typical dissipation rate.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER™ family of data converters from Texas Instruments. It shares the 48-VQFN footprint with other devices in the series but differs significantly in resolution and speed compared to higher-speed pipeline ADCs like the ADC3244. The ADS8472 series is designed for applications prioritizing precision and low power over ultra-high bandwidth.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers for the ADS8472IRGZR were not identified in the provided source material. Designers should consult official Texas Instruments documentation for current lifecycle status and recommended alternatives, as the base ADS8472 model may be marked as not recommended for new designs.
