Feature

Adopts TDA7498 dual-channel power amplifier chip, high power, good sound quality, no distortion, give you a great hearing enjoyment.
Output power: 100W+100W (Vcc = 36 V, RL = 6, THD: 10%); Output power: 80W+80W (Vcc = 34 V, RL = 8, THD: 10%); High efficiency: 90%
Adopts 36-pin PowerSSO packaging with exposed pad up (EPU), that is more convenient to mount a separate heatsink.
Provided with short-circuit protection and over temperature protection, besides, it has high efficiency which is up to 90%.
Has three kinds of modes: standby, mute and normal working mode (you can set the mode by shorting the pins shown on pictures).

High efficiency: 90%

3 Modes:
(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.
