5.3 LINE Voltage Resistor Network

The LINE voltage resistor network can be split between a 78M6610+PSU (daughter) board and the host

board. The 750 Ω termination resistor and anti-aliasing capacitors should be placed near the

78M6610+PSU’s analog input pin.

The high voltage 1 MΩ resistors can be placed remotely on the host board.
