High Efficiency: Depending on the number of analog channels and the complexity of the circuits, the power requirement on the isolated side can be in the range of 0.5 W to 1 W. To reduce the power dissipation in the tightly packed and small form factor modules, and to reduce the current draw from the backplane, the isolated power supply must be very efficient.

Low Electromagnetic Emissions: The cables attached to the AI modules act like transmitting antennas, so the isolated DC-DC must have very low emissions.

Flexible Output Voltage: Depending on the design requirements +/-15 V, +/-5 V or 5 V isolated supply voltage may be needed.
