ADS8471IBRGZT

Analog To Digital Converters (ADC) Overview

The ADS8471IBRGZT is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and supports pseudo-differential or single-ended input configurations. The device features an internal oscillator and allows for both external and internal reference types. It requires an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply voltage between 2.7 V and 5.25 V. 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. The component is housed in a 48-VQFN package and functions within a temperature range of -40°C to +85°C.

• Test and measurement equipment needing precise analog signal digitization

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IBRGZT' against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure that the 48-VQFN package dimensions align with your PCB footprint constraints. Confirm that the operating temperature range of -40°C to +85°C meets your environmental conditions. Check for any recent product lifecycle notices regarding availability or recommended replacements before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution with 1 MSPS throughput is required. It is suitable for applications demanding low power consumption and high accuracy with DNL and INL within +/- 1 and +/- 2 LSB respectively. Consider the parallel interface requirement and the need for separate analog and digital power supplies during system design. Evaluate if the pseudo-differential input capability sufficiently addresses your noise rejection needs compared to fully differential alternatives.

Analog To Digital Converters (ADC) Part Context

The ADS8471 belongs to the ADS847x family of micro-power, 16-bit SAR ADCs from Texas Instruments. This series is designed for applications requiring high precision and moderate speed. The I-grade variant indicates industrial temperature rating capabilities. The RGZT suffix denotes the 48-VQFN package type and tape-and-reel packaging format for automated assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8472IBRGZT is a related part within the same family offering improved linearity performance with lower INL and DNL values. Designers requiring higher accuracy may consider the ADS8472, noting differences in power consumption and specific electrical characteristics. Verify pin compatibility and software configuration differences when substituting between these models.
