how to add gain to amp

:D hi tim,

you did not specify what amp you are referring to, however i will presume it is an IC amp, but then again we dont know what IC amp is that.

the usual way is to put a feedback resistor.

here is the formula to use to calculate the gain: for Non-inverting input - Gain = 1 + feedback resistor/resistor in

for Inverting input - Gain = feedback resistor/ resistor in

hope this would help :D
