This amplifier is from Motorola's 1990 Linear Databook. The circuit can be used with operating amplifiers with the same characteristics and the power supply must be symmetrical.
The gain of this amplifier is 10 times and the excursion to the output voltage is 6.0 V (peak to...
The frequency of this circuit depends on the crystal. The transistor supports a modern equivalent. We...
This circuit uses the SQ3524, a switching integrated circuit. The circuit was found in the April...
