Looking at the circuit diagram it follows the classic op-amp with a long-tailed pair of NPN transistors driving a PNP gain stage and finally a complimentary emitter follower as an output buffer.

Across the two block diagrams of Fig. 2.A & Fig. 2.B, the feedforward gain and the feedback factors are exactly the same when observed strictly with respect to (w.r.t.) the subtraction block input or ...

Consider a differential op-amp circuit that has a positive input with gain of +5 and a negative input with gain of –5 (Fig. 1). R F was selected to be 100 kΩ.

If you have read my first blog, you may have noticed that I really like op amps. My primary expertise lies in designing them, but I’m also intrigued by clever op-amp application circuits. To promote ...

Looking like a handy thing to use at the front end of circuits in lively voltage environments, Analog Devices has introduced a precision op-amp that can function with up to 70V on its inputs ...

Also, the composite buffer in Figure 2 completely eliminates power-dissipation-related errors in the op-amp input.1 C9 and C10 can be replaced by adjustable shunt regulators and R3 and R4 by ...
