ADS7861EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS7861EB/2K5 is a dual-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features simultaneous sampling at a rate of 500 kSPS per channel. The device utilizes a successive approximation register (SAR) architecture and operates with a single power supply ranging from 2.7 V to 5.5 V. It includes an internal voltage reference and supports serial communication via a standard SPI-compatible interface. The component is housed in a 24-pin SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel simultaneous sampling capability for synchronized data acquisition
• Internal voltage reference eliminates the need for external components
• SPI-compatible serial interface reduces pin count and simplifies system integration

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel monitoring
• Data acquisition systems for sensor signal conditioning
• Medical instrumentation involving physiological signal capture

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'B' against the official datasheet to confirm package type and temperature range specifications. Ensure the ordering part number matches the required tape-and-reel quantity of 2500 units. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and current lifecycle stage before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required at 12-bit resolution. It is suitable for applications needing low power consumption within a 2.7 V to 5.5 V supply range. Consider alternatives if higher channel counts or faster sampling rates are necessary.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS786x family of dual-channel ADCs from Texas Instruments. It shares architectural similarities with the ADS7861E but may differ in packaging or environmental rating due to the 'B' suffix. The family is designed for general-purpose data acquisition tasks requiring moderate speed and resolution.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7861E is a direct functional equivalent within the same product line. Verify package compatibility and operating temperature ranges when substituting. Other family members like the ADS7863 offer higher speeds but may require different power management strategies.
