Selected OpAmp characteristics

This is just a small collection of OpAmps that I’m currently using and their relevant characteristics (note that relevant characteristics means relevant to me, this is not a general statement).

If you’re interested in basic operational amplifier circuits I’ve also written a short blog article about the absolute basics.

OP Amp	Open Loop Gain	Gain	Input Impedance (Common Mode)	Input impedance (Differential)	Bias current	Bandwidth	Vcc	GBWP	ESD	Datasheet	Comments
