Description:
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.
 
Mode:
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.    

Package Includes:
1 x TDA7498 Amplifier BoardAdopts 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 = 6ω, thd: 10 percent ); output power: 80w+80w (vcc = 34 V, RL = 8ω, thd: 10 percent ); high efficiency: 90 percent
Wide range single power supply: 15-34vdc(recommended 24V), differential inputs minimize common-mode noise
Applicable speaker impedance: 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
With Standby, mute features: short the points Shown on pictures to be Standby or mute, also can be vacant; with short-circuit protection, over temperature protection
