The TDA7293 is also very efficient, with an efficiency of up to 85%. ### 2. Circuit Diagram The following is the best sounding TDA7293 amplifier circuit diagram PDF: [Image of TDA7293 amplifier circuit diagram] This circuit diagram shows a simple TDA7293 amplifier that can be built using a few common electronic components. The circuit uses a single 12V power supply and can deliver up to 25 watts of power per channel into a 4-ohm load. The TDA7293 is configured as a single-ended class AB amplifier. The input signal is amplified by the TDA7293 and then sent to the output stage, which consists of two NPN transistors. The output stage is biased to operate in class AB, which provides a good compromise between power efficiency and distortion. The circuit also includes a number of protection features, such as a thermal shutdown circuit and a short-circuit protection circuit. These features help to protect the TDA7293 from damage in the event of an overload. ### 3. Construction The TDA7293 amplifier can be constructed using a few common electronic components. The following is a list of the components that you will need: * 1 x TDA7293 amplifier chip * 2 x NPN transistors (such as 2N3904 or 2N2222) * 4 x 100uF capacitors * 2 x 10uF capacitors * 2 x 10k resistors * 1 x 47k resistor * 1 x 1k resistor * 1 x 0.1uF capacitor * 1 x 9V battery * 1 x breadboard * 1 x set of jumper wires Once you have gathered the necessary components, you can begin construction of the amplifier.
