    Thread Summary
    
                The user inquires about the MAX4940EVKIT+ operation and output voltage issues. The final answer clarifies that VPP1 does not need to be 100V, but VPPx and VNNx pins must be connected to appropriate supplies to ensure correct output levels. The 20mA current limit is for a single channel, not the total for two channels.

    Hi, Dear
    

    

    MAX4940EVKIT+
    

    1.Please confirm if the board only can work when the VPP1 is 100. The output is 3.3V when the VDD is 5V, VCC is 12V, VEE is 12V. What's the problem?
    

    2.Please confirm 20mA for singel channel or the total DC for 2 channel.
    

    Hope I can get the reponses ASAP.
    

      
    

    

    Thank you.
