Stereo 3W Audioverstärker - PAM8403
- Power: DC 3.6V - 5.5V
- Output power: 3W +3 W
- Signal-to-noise ratio: 90dB
- Efficiency:> 90%
Power positive and negative can not be reversed, the power supply
voltage must not exceed 5.5V, two violations could result in damage to
- On-chip high-gain buffer, there can be no changes to board
any element parameters, does not meet the parameters will result in IC
- 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.
- 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.
