Hi,

For inamp AD8221 the maximum supply voltage is +/-18V, in my application i will be using ad8221 with  bipolar supply and with a gain of 500 to 1000,

The input signal range will be 0.5mV to 1mV, for a gain of 1000 the output voltage will be 0.5V to 1V. so in this case  please suggest me whether i need to go for +-3.3V or +-5V, or any other. And also the other parameters i should look into.

 

 

Thanks,

Thejesh
