The circuit shown in the figure can be designed with more modern operational amplifiers, as it is from 1994 documentation by National Semiconductor. The power supply must be symmetrical.
With an output power of 1.5 W under a 12 V supply, this circuit makes use of transistors that are...
I got this circuit from Hands-On Electronics, 1988. The American magazine no longer exists, but...
This circuit is from the Motorola Linear Databook of 1990. The values of the components depend on the...
