ADS7863ADBQ

Analog To Digital Converters (ADC) Overview

The ADS7863ADBQ is a dual, simultaneous-sampling analog-to-digital converter (ADC) from Texas Instruments. It features two 12-bit Successive Approximation Register (SAR) converters housed in a 24-pin SSOP package. The device supports a sampling rate of 2 MSPS per channel with an SPI digital interface. It accepts differential or pseudo-differential inputs and operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 71.5 dB and a power dissipation of 45.3 mW. The component functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between channels for high-fidelity signal acquisition.
• Integrated internal voltage reference simplifies system design by reducing external component count.
• Flexible input configuration supports both differential and pseudo-differential modes for versatile sensor interfacing.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ADBQ' against the manufacturer's official datasheet to confirm the exact package type and temperature grade. Ensure compatibility with existing PCB footprints for the 24-SSOP form factor. Confirm that the required sampling rate and resolution meet the application specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of multiple signals is critical to maintain phase integrity. Compare the 2 MSPS throughput against slower multiplexed ADCs if channel isolation is required. Evaluate the 12-bit resolution against higher precision alternatives if noise immunity is a primary concern.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7863A family of dual SAR ADCs. It shares architectural similarities with single-channel variants but provides integrated dual conversion capabilities. The device is designed for applications demanding high speed and accuracy without the complexity of external synchronization circuits.

Analog To Digital Converters (ADC) Replacement Considerations

Check for ADS7863ARGER or ADS7863IRGET as potential pin-compatible alternatives with different packaging or temperature ratings. Verify functional equivalence regarding sampling rates and input configurations before substitution.
