AMC1311-Q1: VcmOUT range

Part Number: AMC1311-Q1


Hi,

AMC1311B fail voltage is about 2.7V / 0.3V, and the VCMout range is 1.39V to 1.49V

so when the VCMout is 1.39V or 1.49V, the fail voltage is still in 2.7V / 0.3V, or will above 2.7V, under 0.3V?

Thanks for apply

    Hi,

    Please refer to the electrical characteristics table; V_Failsafe for reference. The maximum fail-safe output voltage is -2.5V. This value can be divided in two and added/subtracted to the VCMoutput range to calculate their absolute values.
