Op amps are pretty dang cool, with a lot of neat circuits you could build using them. I actually just put the finishing touches on my first actual op amp design and sent the design files over to ...

Non-inverting amplifier. The first common op amp configuration we will look at is the non-inverting amplifier (Figure 2). I always wonder why we don’t call this the “regular amplifier” configuration ...

The differential amplifier circuit (also sometimes referred to as a long tailed pair) here formed by Q2 and Q3 is the signature of an op-amp, and all integrated circuit op-amps will incorporate ...

Fig. 3: Basic Non-Inverting Amplifier Fig. 3 is the same non-inverting configuration but set up to achieve some value of gain as set by the addition of resistors R1 and R2. This arrangement provides ...

Building on last month’s discussion of resistor noise, let’s check out some basics of amplifier noise.The non-inverting op amp configuration is most common for low noise applications so we’ll make ...

The 741 was the first two stage, internally compensated, high-gain, low-cost, op amp. “I thought up the idea of internal compensation to avoid the instability seen in the 709,” said Fullagar. “The ...

The Analog Engineer’s Circuit Cookbook: Op Amps is an example. It compiles more than 25 popular op-amp circuit designs like current sensing, attenuating, and full-wave rectifying into a single e ...

2. In the non-inverting amplifier circuit, balance resistor RB makes the analyses from both perspectives agree and protects the op amp. To protect the op amp and provide a way to balance the ...
