LM324 uA741 TO072 and i know most of them are poor i used LM358 as first amplification which made a gain approx 100 then i used anther one but it ends up with complete unstable system and i am thinking of building instrumentation amplifier from one of the above Op/Amps. 05% accuracy. use LM358 with two feedback resistors, then you can get non-inverting output value. 001µF IB 3R 3MΩ IB Inputcurrent compensation eo I B e I 1/4 LM124 Zo ZI C 1µF 2I B R 1MΩ 2IB * Polycarbonate or polyethylene * 124-19.

Meskipun untuk kebutuhan yang lebih presisi lagi, akan lebih baik apabila memakai IC Instrumentation Amplifier seperti INA101, INA110, OP77 dll (sayangnya di pasar agak susah. Now have a gain of 30 in the OP07 and a gain of 10 in LM324 then 30 * 10 = 300. A differential amplifier circuit is a very useful op-amp circuit, since it can be configured to either "add" or "subtract" the input voltages, by suitably adding more resistors in parallel with the input resistors. The present circuit shows only one Instrumentation Amplifier stage, which takes input signal from sensor.
