    Hello,

    24V is fine, but as you recognize, 32V is not. 

    For ALM2403-Q1, we specify 26V Vs as ABS max. 

    What does this supply voltage waveform versus time look like? Is this stating that there are occasional 32V spikes, or a chance that the supply voltage is fixed at 32V?

    Something like a simple Zener diode may offer some protection to the device during short over-voltage events. 

    If longer duration overvoltage events occur, a more robust over-voltage device like TPS2400 or a dedicated voltage regulator may be necessary. 

    Please let me know if you have any questions.

    Best,

    Jacob
