Chipskey XH-M179 PAM8403 Amplifier Module High Power 2-Channel 3W Audio Super Mini Digital Amplifier Circuit Board

Features:

Special internal output processing circuit , eliminating the conventional LC network , EMI values lower than the LC ! Maximum power output at a lower voltage , super-power , internal electronic switch stand , built-in high -gain buffer amplifier built in short circuit protection."Power": 3.6 to 5.5V, single-cell lithium battery or USB -powered appropriate, also be four 1.2V batteries, power transformers must add 5V regulator circuit chip will burn more than 5.5V .

Parameters:

Power supply : DC (DC): 3.6v-5.5V
Output power : 3W +3 W (4 ohms)
SNR : 90dB
Efficiency: >90%
Size : 24 * 15.5 * mm positioning hole size : 20mm aperture spacing : 2mm

Note:

1 : The power of positive and negative can not be reversed , the supply voltage must not exceed 5.5V, these two violations could result in IC damage.
2 : On-chip high- gain buffer , the board can not change any component parameters do not meet the parameters will result in IC damage.
3: Please try to use the line input cable with shielded, can play a role in anti-interference , eliminating clutter current sound.
4 : output cmos tube BTL drive mode, the speaker can not be negative about together , that is connected to the speaker four lines are completely independent, does not allow total access !
