ADS8902BRGER

Analog To Digital Converters (ADC) Overview

The ADS8902BRGER is a 20-bit, high-speed successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an integrated reference buffer and an internal low-dropout regulator (LDO). The device operates with a single analog supply voltage ranging from 3 V to 5.5 V and supports digital logic interfaces compatible with 1.65 V to 5.5 V supplies. It utilizes the multiSPI digital interface for communication. The component is housed in a 24-lead VQFN package and is designed for applications requiring high precision and speed.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BRGER against the manufacturer's current datasheet to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the 24-VQFN package dimensions. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 20-bit resolution and high sampling rate are required within a compact form factor. The integrated reference buffer and LDO make it suitable for designs aiming to minimize external component count. Compare performance metrics such as SNR and power dissipation against other SAR ADCs in the same family if system constraints allow.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS890xB series of 20-bit SAR ADCs. It shares architectural similarities with other members like the ADS8904B and ADS8910B but offers distinct integration levels regarding internal regulators and buffers. It serves as a high-performance solution within Texas Instruments' portfolio for precision analog-to-digital conversion tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS8904BRGET or ADS8910BRGET, depending on whether 18-bit or 20-bit resolution is acceptable. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
