Tda7293 Bridge Amplifier Circuit. Thermal pad circuit of dynamic amplifier using tda 7294 180watts bridge or stereo 2 x 80watts click to enlarge. The main benefit of the mosfet stage is that it doesnt need such radical protection circuitry as a bipolar stage so unpleasant protection circuit artefacts are eliminated.
Carlsbro glx100 marshall mg and marshall mode four contains tda7293 7294 circuits. The integrated circuit body should be insulated from the heatsink using mica or plastic thermal pad to insulate the screw. The device is using the bcd technology a mixed bipolar and power mos devices.
The main benefit of the mosfet stage is that it doesnt need such radical protection circuitry as a bipolar stage so unpleasant protection circuit artefacts are eliminated.
The tda7293 is a monolithic integrated circuit in multiwatt15 package intended for use as audio class ab amplifier in high fidelity applications. This is more than enough for small rooms or rock clubs for live sessions with very good for example eminence speakers.
