ADS8634SRGER

Analog To Digital Converters (ADC) Overview

The ADS8634SRGER is a quad-channel, 12-bit analog-to-digital converter (ADC) utilizing successive approximation register (SAR) architecture. It supports single-ended bipolar input signals and operates with an analog supply voltage ranging from 2.7 V to 5.25 V and a digital supply voltage from 1.65 V to 5.25 V. The device achieves a sampling rate of 1 MS/s per channel with a signal-to-noise ratio (SNR) of 71.8 dB and SINAD of 71.3 dB. It features an SPI interface, internal or external reference options, and a built-in comparator. Power consumption is rated at 14.45 mW, and it functions within a temperature range of -40°C to +125°C in a 24-pin VQFN package.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GER' against the manufacturer's official datasheet to confirm package type, tape-and-reel specifications, and moisture sensitivity level. Ensure compatibility with required operating temperatures and supply voltages before integration. Cross-reference the component marking code with official documentation to prevent counterfeit substitution during sourcing.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four independent 12-bit channels are required at 1 MSPS. Compare SNR and power dissipation against alternative SAR ADCs if system noise budgets are tight. Verify that the single-ended input configuration meets the source impedance requirements of the application signals.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8634 family of low-power, 12-bit ADCs from Texas Instruments. It shares architectural similarities with other members of the series but is distinguished by its quad-channel configuration and specific pinout in the VQFN-24 package. It complements the company's broader portfolio of precision data converters designed for industrial and automotive environments.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible alternatives within the ADS86xx series. Verify electrical parameter equivalence, particularly sampling rate and SNR, when considering cross-brand replacements. Ensure interface compatibility remains unchanged.
