ADS7822EB-1/2K5

Analog To Digital Converters (ADC) Overview

The ADS7822EB-1/2K5 is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a high-speed sampling rate of 200 kSPS and operates on a single analog supply voltage ranging from 2.7 V to 5.25 V. The device utilizes a 3-wire serial interface compatible with standard SPI protocols, facilitating easy connection to microprocessors. Designed for low-power applications, it consumes approximately 1.6 mW at full speed. The component is housed in an 8-pin VSSOP package and supports pseudo-differential or single-ended input configurations.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1' against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics relative to the standard ADS7822EB variant. Ensure the '/2K5' designation aligns with the required reel quantity for manufacturing integration. Cross-reference the datasheet revision date to ensure compliance with current RoHS standards and material declarations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate speed (200 kSPS) and low power consumption is required for 12-bit precision. The external reference requirement allows for flexibility in system design but necessitates careful selection of a stable reference voltage source. Consider the VSSOP-8 package constraints for PCB layout and thermal management in compact enclosures.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7822 family of micro-power ADCs from Texas Instruments. The family includes variants with different packaging options such as SOIC-8 and MSOP-8, and varying sampling rates like 75 kSPS. The ADS7822 series is designed for applications requiring small form factors and efficient power usage in battery-operated environments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include ADS7822E/2K5 and ADS7822EC/2K5, which share similar electrical specifications but may differ in package type or temperature range. Verify that any substitute maintains the 200 kSPS speed and 12-bit resolution while fitting the 8-pin VSSOP footprint.
