I want to amplify a voltage range (from 0.54 mV to 42 mV) in below circuit which the gain of the Op Amp is 10x, so the Vout will be (5.4 mV : 0.42 V) ..
and this Vout will be a Vin again in another non-inverting Op Amp to be amplified 10x so the final Vout will be (54 mV : 4.2 V)
Question What's the Vdd that must be supplied to the Op Amps in both amplifying stages to get these Vouts --the Supply has to be 2.5 volts only--?
