This blog includes many interesting circuits which incorporates the IC 741 as the main active component for implementing the proposed functions. The present post explains yet a couple of more useful IC 741 application circuit ideas especially designed for the new electronic hobbyists.
The first circuit diagram shows how the IC 741 can be configured as a high power amplifier circuit. Though the maximum power of this amplifier is not more than 4 watts, the amplifier provides relatively good response with the applied frequency. The distortion of less than 0.5% and has a bandwidth of over 20kHz. The amplifier requires a minimum input of around 150 mV.
Best yet cheap CAR AMPLIFIER you can buy.
The next circuit shows the IC 741 being wired up for providing a regulated power supply with an output which can be varied as per ones own requirement.
Basically the IC is configured as a comparator cum driver for the proposed power delivering purpose. The employed zener diode has been included for fixing the non inverting of the IC with a constant refernce voltage.
An additional transistor BC107 has been included for making the circuit short circuit proof and also overload protected.
The output volts can be varied by adjusting the 10 K pot while the maximum current can be set by selecting or varying the 0.6 Ohm resistor appropriately as per the needs.
