10W/20W/30W Class-D audio power amplifier module Wide supply voltage range
10W/20W/30W Class-D audio power amplifier module Wide supply voltage range 12V/24V DY-AP3001 Electronic Characteristics Product Name 30W audio power amplifier module Product Model DY-AP3001 Supply voltage DC: 8~24V Work mode Class-D(PWM modulation) Output mode Mono Input mode Default single-ended(differential input is available) Input impedance 1k Output load 4-8 Output power(@1KHz) 30W @16V 4 20W @12V 4 10W @12V 8 15W @16V 8 25W @24V 8 Speaker selected(30W~300W) 4(8~16V supply) 8(8~24V supply) Application circuit PCB Size Package NOTE: 1.8~24VDC is recommended; upper than 26V, it will be damaged. 2.Driving 4 load, power supply must be under 16V; and driving 8 load, supply must be under 24V. 3.The supply current must be 2A at least. 4.Inverting power supply is not permitted, or the chip will be damaged. 5.The module is designed for audio signal range 0.5V~1.5V. 6.The line connecting speaker with module should be within one meter. 7.ESD protection , please release ESD on your hands before you contact the module. 8.30W and upper power speaker is recommended. Fault Check 1. The speaker tapped when power on. 1) Check that the speaker load is so small that the current through the speaker is enough for chip goes into DC protection. Try to lower the supply and restart. 2) Check that if the power supply is low that cannot drive the speaker. 2A power supply current is ok. 2. Floor noise in speaker when playing 1) Play another music to verify the noise is not related with music itself. 2) Short the input-end of module to verify the noise is not related with the module itself. 3) Replace better audio line to check if the noise is caused by the audio line because of low quality. 4) Replace the speaker to check If the noise is caused by speaker itself. 5) Replace the power supply to check If the noise is caused by unstable power. 3. The temperature of speaker is very high Replace with bigger power speaker
