ADS8471IRGZR

Analog To Digital Converters (ADC) Overview

The ADS8471IRGZR is a 16-bit, 1 MSPS pseudo-differential Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Texas Instruments. It 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. The device features a parallel interface and supports both external and internal reference configurations. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 93 dB, Differential Nonlinearity (DNL) of +/- 1 LSB, and Integral Nonlinearity (INL) of +/- 2 LSB. Power consumption is rated at 220 mW, with a maximum power dissipation of 240 mW. It functions within a temperature range of -40°C to +85°C and is housed in a 48-pin VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the operating temperature grade 'I' corresponds to the industrial range of -40°C to +85°C. Ensure compatibility with the required 48-pin VQFN footprint during PCB design. Check RoHS compliance status through official manufacturer documentation prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-resolution 16-bit conversion at moderate speeds up to 1 MSPS. Consider the parallel interface requirements and the need for separate analog and digital power supplies. Evaluate the SNR and linearity specifications against system accuracy needs. Verify that the VQFN-48 package fits the available board space constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8471 series of SAR ADCs from Texas Instruments. It shares the same core architecture and pinout as the ADS8471IRGZT, differing primarily in the tape-and-reel packaging format indicated by the 'R' suffix. Both variants offer identical electrical characteristics and functionality within the industrial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8471IRGZT is a confirmed equivalent part number offering identical electrical specifications and functionality, distinguished only by its cut-tape packaging format instead of reel packaging.
