Power-Supply Bypassing and Grounding
The MAX6339 is normally powered from the monitored
IN2 supply input. All monitor inputs are immune to short
supply transients. If higher immunity is desired in noisy
applications, connect 0.1μF bypass capacitors from the
IN2 input to ground. Additionally, capacitance can be
