Hi ! in theory Opam.. It's simple to use an opam ?
ex : 1mV_Peak (source) f= 50Hz. if I want the output 1 V_peak. so the gain I need is 1000k. ( If I choose the supply source +-5V, and the value of R1 = 1K, Rf = 1M . in the inverting amplifier the gain = - Rf/R1 = 1000/1 = 1000.
Vout = 1mV_peak*1000 = 1V_peak.
But It's ideal.The Datasheet of any Opam show me a lot information That makes me confuse How I use there information.
EX : LM 324 ..
Low input bias current: 20nA
Low input offset 5mV max
Low input offset current 2nA
Large volt gain 100 db
IF I desig a cuircuit to amplify a signal from a sensor ( ac volt at terminal).
What should I have to pay intention ? How to choose the Resistor ?
Some parameter of LM324 obout What do I do ?
