Features:
100W+100W dual-BTL class-D audio amplifier with single power supply
Amplifier chip: TDA7498
Wide range single power supply: 15-34VDC(recommended 24V)
Output power: 100W+100W (Vcc = 36 V, RL = 6Ω, THD: 10%)
Output power: 80W+80W (Vcc = 34 V, RL = 8Ω, THD: 10%)
Speaker impedance: 4-8 ohm (8 ohm best, 4 ohm or 6 ohm also works)
Four fixed gain settings available: 25.6 dB, 31.6 dB, 35.1 dB and 37.6 dB
Adopts differential input to minimize common-mode noise
Protection: short-circuit protection, over temperature protection
With standby and mute features
High efficiency: 90%
Note: Packaging with exposed pad up (EPU), more convenient to mount a separate heatsink

Mode:
Three kinds of modes avaliable: standby/ mute/ normal working mode
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 module works normally.
