AMC1200: AMC1200 high side supply missing

Other Parts Discussed in Thread: AMC1301

Hi,

I would like to know,

what is the output voltage of an AMC1200 amplifier if i gave an input differential signal(with 250mV range) but the high side supply(VDD1) is missing?

what is the output voltage of an AMC1200 amplifier if i gave an input common mode signal of range 3V with high side supply of 5V ?

Does it have any fail safe output voltage like AMC1301?

Thanks in advance,

Naveen.

    Hi Naveen,

    The AMC1200 does not have any fail safe operation.  Because of that, if high side power is removed, the outputs could go to either FS+ or FS-.  The only common mode restriction is VDD1 to -160 mV.
