The TDA7498 is a 100W+100W dual-BTL class-D audio amplifier with single power supply designed for home theater and active speaker applications. It adopts 36-pin PowerSSO packaging with exposed pad up (EPU), more convenient to mount a separate heatsink.
The TDA7498 has three kinds of modes: standby, mute and normal working mode(you can set the mode by shorting the pins shown on pictures).
Standby mode: all circuits closed, at a low power state;
Mute mode: all input signals connects ground, the duty cycle of forward/backward PWM output signal is 50%;
Normal working mode: the amplifier works normally.
