ADS8472IRGZTG4

Analog To Digital Converters (ADC) Overview

The ADS8472IRGZTG4 is a 16-bit, 1 MSPS successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a parallel interface and supports differential or pseudo-differential input configurations. The device operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply 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. It is housed in a 48-pin VQFN package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal oscillator eliminates the need for external clocking circuitry.
• Supports both differential and pseudo-differential input modes for flexible signal conditioning.
• Offers high linearity performance with low integral and differential nonlinearity specifications.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition.
• Medical instrumentation such as ultrasound and patient monitoring devices.
• Test and measurement equipment including oscilloscopes and spectrum analyzers.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance when sourcing. Confirm the operating temperature grade matches the 'I' designation for industrial ranges. Ensure the package type corresponds to the 48-VQFN footprint required for the target PCB layout. Check for any recent product change notices regarding packaging or material declarations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-precision ADC with a parallel interface is required. Compare against the ADS8471 if pseudo-differential inputs are sufficient, noting differences in linearity specs. Consider the ADS8472IBRGZT if the commercial temperature grade is acceptable instead of the industrial grade. Evaluate power consumption requirements against the typical 225 mW dissipation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8472 family of micro-power SAR ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS8471 but offers improved linearity characteristics. The device is designed for applications demanding high accuracy at moderate sampling rates. It complements Texas Instruments' portfolio of precision data converters for industrial and medical markets.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8472IBRGZT is a pin-compatible alternative with a commercial temperature range. Verify that the lower linearity specifications of the IB variant meet system requirements. No direct functional substitutes with different interfaces are recommended without significant redesign.
