Tda7293 amplifier circuit diagram.

In the circuit of the tda7293 100w amplifier circuit the dc diaphragm capacitors must be added in addition to the bridge diode. Previously the tda7293 100w dmos audio amplifier integrated with the amplifier circuits were shared this circuit is considered the same with others but the tda7293 pcb design is very small and regular. While the board is designed to take two tda7293 ics it can naturally be operated with only one and the pcb is small enough so that this is not an inconvenience. Tda7293 amplifier circuit diagram.

The power supply consists of bridge rectifier and huge electrolytic capacitors ranging from 4 7μf to 12μf the series combination of resistors and leds discharge the capacitors. Power amplifier using the tda7293 chip manufactured by st microelectronics includes schematic and pcb design for easy mounting of the power amplifier the tda7293 is a monolithic integrated circuit in multiwatt15 package intended for use as audio class ab amplifier in hi fi field applications home stereo self powered loudspeakers top class tv. The amplifier has on board power supply and to power the circuit it requires just a transformer.
