ADS7863ADBQR

Analog To Digital Converters (ADC) Overview

The ADS7863ADBQR is a dual 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features two independent ADCs with a sampling rate of 2 MSPS and supports 4 or 6 input channels via an internal multiplexer. The device operates on a single supply voltage ranging from 2.7V to 5.5V for both analog and digital domains. It utilizes a 24-SSOP package and provides a serial SPI interface for data output. Key electrical characteristics include synchronous sampling capability, differential or pseudo-differential input types, and an operating temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates two independent 12-bit SAR ADCs with simultaneous sampling capability for precise multi-channel acquisition.
• Features an internal multiplexer supporting flexible configuration of 4 or 6 input channels with differential or pseudo-differential inputs.
• Provides a high-speed serial SPI-compatible interface for efficient data transfer and system integration.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal monitoring

• Medical instrumentation devices needing synchronized channel sampling

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Check for any recent product change notices that may affect pinout or electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization is required at 12-bit resolution and 2 MSPS speed. Ensure the application supports the 2.7V to 5.5V supply range and utilizes a compatible SPI controller. Verify that the 24-SSOP package dimensions fit the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7863A family of dual-channel SAR ADCs. It shares core architecture with variants like the ADS7863ARGET but differs in packaging. The ADBQR suffix specifically denotes the 24-SSOP surface-mount package variant within the broader ADS7863 series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7863ARGET offers identical functionality in a VQFN-24 package. Verify pin compatibility and thermal performance differences before substitution.
