ADC Selection Guide for Industrial Applications

Selecting the right ADC is critical for achieving accurate measurement, stable signal acquisition, and reliable system performance in industrial and precision applications.

This guide compares three devices with different architectures:

• AD7689: Cost-effective solution for general-purpose multi-channel acquisition
• AD7699: Higher precision and lower noise for demanding measurement systems
• AD7606: Simultaneous sampling with ±10V input for industrial environments

Key Selection Considerations

• Precision: Choose AD7699 for higher accuracy and better signal fidelity
• Synchronization: Use AD7606 when multi-channel simultaneous sampling is required
• System Complexity: AD7689 offers the simplest integration for standard applications

Engineering Value

• Simplifies ADC selection based on application needs
• Improves system accuracy and signal reliability
• Supports scalable design from general to industrial-grade systems
