Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two f… ...

This cable tv amplifier circuit is a rf amplifier designed to be quickly installed between two coaxial cables. Both input and output impedances are compatible with 75 Ω cables. The main amplifier si ...

In circuits 1, 2, and 3, the LM386 inputs are connected directly across the tank circuit and use the LM386 as an RF envelope detector. Circuit 4, with its relatively large value coupling capacitor, ...

This high-resolution audio amplifier delivers exceptional sound quality with a simple yet efficient circuit design. Engineered for powerful performance, it enhances audio output with clarity and ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R ...
