5.4 Shunt Current Sensor

The current shunt network can also be split between the 78M6610+PSU (daughter) board and the host

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

78M6610+PSU’s analog input pins.

The resistive current shunt can be placed remotely on the host board. It is important to provide a wide,

heavy copper path between the current shunt and its connections to high current AC wiring.
