Typical Audio Amplifier Application Circuit LM 4702BTA

300 watt – 1200 watt MOSFET Amplifier

When you need an amplifier with high watt power. For use in applications such as concert, theater, the festivals etc. This circuit is most suitable. Both Loudness and durability, that courage to try. For this circuit, typically the maximum watt power at load 4 ohm equal to 300 watt. or about 200 watt at load 8 ohm. Which the watt power very much this level. If you are not satisfied. Also may added a higher power.


The TA3020 is a two-channel, 300W (4Ω) per channel Amplifier Driver IC that uses Tripath’s proprietary Digital  Power Processing (DPPTM) technology. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
