Audio Amplifier Module, Stereo Dual Channel - PAM8403

Applications

• LCD TVs, monitors
• Laptop
• Portable Speakers
• Portable DVD players, game consoles
• Phone / speakerphone

Features

• Special internal output processing circuit, eliminating the conventional LC network, than the LC lower EMI value.
• At a lower voltage to obtain the maximum power output, the super-power.
• Built-in standby electronic switch.
• Built-in high-gain buffer amplifier.
• Built-in short circuit protection.
• Built with Potentiometer, can adjust the volume & control power switch freely.
• Power positive and negative can not be reversed, the power supply voltage must not exceed 5.5V, two violations could result in damage to the IC.
• On-chip high-gain buffer, there can be no changes to board any element parameters, does not meet the parameters will result in IC damage.
• Input line, please try to use shielded lines, you can play anti-jamming, eliminate clutter current sound.
• Output cmos tube BTL drive way, the negative electrode of the left and right speakers can not be connected together, four lines that connect to a speaker is completely independent, does not allow total access.
