Tda2009 is used in amplifier. An amplifier electronic amplifier or informally amp is an electronic device that can increase the power of a signal a time varying voltage or current.
Loud And Clear Sound Audio Amplifier Circuitmake A Simple Audio
You can use this circuit for sound sensing applications and some automatic robotic sensors.
simple audio amplifier circuit diagram using transistor. Let me show you. Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. The circuit is very simple inexpensive and easy to built.
This mic pre amplifier circuit operated with 9v dc voltage you may use 9v battery for this circuit. Simple low power inverter circuit 12v dc to 230v or 110v ac diagram using cd4047 and irfz44 power mosfet gallery of electronic circuits and projects providing lot of diy circuit diagrams robotics microcontroller projects electronic development tools. It is actually a dual audio power amplifier that is designed specifically for very good quality stereo applications.
The circuit above is essentially a mono channel circuit. It is probably the one of the easiest audio amplifiers to build. Using only four transistors in the quasi complementary amplifier configuration this transistor power amplifier circuit can deliver 90w of power into 4 ohm loads and at low cost.
