ADS7861EBG4

Analog To Digital Converters (ADC) Overview

The ADS7861EBG4 is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features two independent ADC cores capable of simultaneous sampling at a maximum rate of 500 kSPS per channel. The device utilizes a serial interface compatible with standard SPI protocols for data output. It operates from a single 2.7 V to 5.5 V power supply and includes an internal reference voltage source. The component is housed in a 24-pin SSOP package designed for surface-mount applications.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture enabling true simultaneous sampling of two input signals without interleaving errors.
• Integrated internal reference voltage eliminates the need for external precision reference components.
• Flexible serial interface supports standard communication protocols with configurable clock polarity and phase.

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring synchronized multi-channel signal capture
• Industrial process control monitoring
• Medical instrumentation and diagnostic equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BG4' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the revision level to avoid discrepancies in electrical characteristics or timing parameters during procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is critical, as opposed to multiplexed alternatives which introduce time skew. The 12-bit resolution and 500 kSPS speed balance performance with power consumption. Verify that the input voltage range aligns with the sensor outputs before finalizing the design choice.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7861 family of dual-channel SAR ADCs. It serves as a higher-performance alternative to single-channel devices in multi-input applications. The series is designed for general-purpose data conversion tasks where channel synchronization is more important than ultra-high throughput.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7861E: Identical functional specifications but may differ in packaging or reel quantity. ADS7863: Offers higher sampling rates but requires verification of pin compatibility and power requirements.
