2x100W class D amplifier module with TDA7498

Compact audio amplifier in class D from 100 + 100 musical watts, working with single power supply (between 15 and 34 volts) and able to drive two speakers with 8 ohms of impedance (also with 4 ohms and 6 ohms). Based on the integrated TDA7498, it has four gain levels that can be set via dip switches: 25.6 dB, 31.6 dB, 35.1 dB and 37.6 dB, mute and stand-by function, short-circuit and over-temperature protection, fixing holes to facilitate installation.
