ADS7863ARGET

Analog To Digital Converters (ADC) Overview

The ADS7863ARGET is a dual 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features simultaneous sampling capabilities with a maximum sampling rate of 2 MSPS per channel. The device integrates four differential or pseudo-differential input channels and supports both internal and external reference configurations, utilizing an internal 2.5 V reference. It operates on single supply voltages ranging from 2.7 V to 5.5 V for both analog and digital domains. Communication is handled via a high-speed SPI interface. The component is housed in a 24-pin VQFN package and is rated for operation across an extended temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between channels without inter-channel delay.
• Integrated internal voltage reference reduces external component count and simplifies board layout.
• Flexible input configuration supports both differential and pseudo-differential signal connections.
• High-speed serial peripheral interface enables efficient data transfer with minimal pin usage.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ARGET' corresponds to the intended temperature grade and packaging format upon ordering. Confirm that the required sample rate and resolution align with system performance needs. Ensure compatibility with existing SPI controller logic levels. Check for moisture sensitivity handling requirements during storage and assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous multi-channel sampling is critical for maintaining signal integrity. Consider the 12-bit resolution and 2 MSPS speed for balancing precision and throughput. Evaluate power consumption constraints against the 2.7 V to 5.5 V operating range. Compare with lower-speed variants if power savings are prioritized over bandwidth.
