Operational amplifier LMC662

The LMC662 is an operational amplifier with extremely low input current of 2fA (2 femto ampere, the brick’s input resistance is >1 terraohm). It can increase its voltage differences at the inputs (+ and -) up to 126 dB. Operational amplifier need to be wired correctly according to application. As the OA’s inputs are very sensitive to overvoltage it has to be treated especially careful.
