This reference design is a high-voltage analog input module with eight channels. Each channel can be used for both voltage and current measurement. The design uses 16-bit analog-to-digital converter (ADC) ADS8681 that can handle input voltage of up to ±12.288 V. This make any preprocessing of standard input voltages in the industrial space unnecessary. In addition, four channels of the design are able to handle common-mode (CM) voltages of up to ±160 V. Therefore, the user does not need to worry about ground loops or compensation currents flowing between the connected inputs.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
