Introduction
The EK65 Evaluation kit is designed to provide a convenient way to breadboard and evaluate design ideas for the
MP400FC power operational amplifier. The evaluation board is pre-wired for all required external components. The
evaluation board has been laid out and labeled to easily configure the high voltage operational amplifier in a non-
inverting differential configuration for single supply operation using the MP400FC boost supply (Refer to Application
Note 21). However, the evaluation board is flexible enough to analyze a multitude of standard or proprietary circuit
configurations.

Please read this data sheet in it’s entirety before starting to construct your evaluation board.
All APEX amplifiers should be handled using proper ESD precautions.
Do not change connections while the circuit is powered.
Initially set all power supplies to the minimum operating voltage allowed in the device data sheet.
The MP400FC is a high voltage amplifier with an integrated switch mode power supply. Though the input
voltage will be 50V or less, the MP400FC can generate voltages greater then 350V. The high generated
voltage will be present on the evaluation board. Caution must be used when working with the evaluation
board.
