Hi team,

The output voltage of AMC1301-Q1 is equal to (Voutp-Voutn). Can we calculate the Voutp and Vout respectly based on the input voltage and Vcmout? What the equations are?

Thanks!

Hi Lenna,

This is a pretty straight forward calculation - VOUTp on the AMC1301 would be Vin * Gain + Vcmout / 2. VOUTn would be the same except you subtract the Vcmout voltage.

Hi Tom,

From the below figure, the Voutp=Vcmout+(Vinp-Vinn)*Gain/2, Voutn=Vcmout-(Vinp-Vinn)*Gain/2. Please help check it.

Sorry - forgot the /2 (coffee hadn't kicked in yet).
