2.1 Block Diagram

This reference design showcases the following configurations for improved system performance:

• 16-bit ADC ADS8686S based 16-channel analog input module
• 16-bit ADC ADS8686S based isolated interface module
• ADS8688A-based, 16-channel input with dual SDO for measurement of AC or DC analog input
• ADS8688A-based, isolated, 16-channel input with dual SDO using digital isolators with integrated power

The architecture choice depends on the size, input range and need for alarm features.
