5Pcs Cjmcu 832 Pam8302 25W Single Channel Class D Audio Power Amplifier Development Board For Arduino

Description : This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient (over 90 procent efficient when driving an 8 speaker at over half a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. Theres even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. This board is a welcome upgrade to basic LM386 amps. CJMCU The A and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully differential - if you dont have differential outputs, simply tie the Audio- pin to ground. The output is Bridge Tied - that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250KHz square wave P Lees meer over de 5Pcs Cjmcu 832 Pam8302 25W Single Channel Class D Audio Power Amplifier Development Board For Arduino van huismerk in de productgroep elektronica
