Product Details

Product Size

Product Features:

Output short circuit protection
Mini small size, easy to install
30W dual channel, no heat sink

Pin definition

1.CS: chip select (floating or high, boot; low, off)

2.INR: Right channel audio signal input positive

3.AGND: audio signal input common ground

4.INL: left channel audio signal input positive

5.GND: power ground

6.VCC: sound power positive

7.SPL +: left channel output positive, then horn +

8.SPL-: left channel output negative, then speaker -

9.SPR +: right channel output positive, then horn +

10.SPR-: Right channel output negative, then speaker -

Other

Power amplifier board, then the horn between the two pads DC voltage 0V, between the speaker pad and GND DC voltage is half of the power supply voltage.
Use 4 oh speakers, the maximum power supply voltage can not exceed 16V, otherwise the chip is too high heat damage to the amplifier. Use 8 ohm speakers, the maximum power supply voltage can not exceed 24V, otherwise the voltage is too high breakdown power amplifier chip.
Speaker wiring as far as possible with the control of the sound line within 3 meters, the line is too long load inductance increases and produce self-inductance voltage is too high breakdown power amplifier chip, long-term speaker recommended to consider the diode (IN5819) to achieve self-induced voltage release Protect the chip.

Precautions:

Power amplifier board power, the hand can not touch the board components on the chip, because the human interference signal interference digital amplifier timing, resulting in damage to the chip, as well as the body with static power in the case of direct breakdown of components, Basic common sense we still want to popularize the next.
Power supply voltage to be stable, as far as possible the use of switching power supply and battery power supply, if the power ripple is too serious, you can add capacitance filter. Battery-powered without additional capacitor filtering. Power supply must not exceed the board operating voltage, or burn the chip, digital amplifier special Jiaoqi, better than analog power amplifier, work completely different.
8 ohm speakers basically do not need to add heat sink, less than 8 ohm speakers, if the chip temperature is higher than 60 degrees, because immediately stop working, plus heat sink fan, otherwise the temperature will immediately burn the chip.
