UNDERSTANDING AUDIO ICs The integrated circuit audio amplifier has many advantages over amplifierswhich are built from separate, individual components. An IC allows more advanced circuits, with fewer components. A single IC can contain the equivalent of a score or more of transistors, diodes and resistors, matched and encapsulated together.
Simple Audio Pre-Amplifier - Schematic Design
https://circuitdiagram.net/simple-audio-pre-amplifier.html
This is a simple audio pre-amplifier circuit using single transistor 2N3904. This easy circuit provides good gain to weak audio signals such as electret microphone. Use it in front of an RF oscillator to make an RF transmitter that’s very sensitive to sound. Power supply used for this circuit is wide range from 3VDC to 9VDC, you may choice the middle range about 6VDC to …
