PAM8302 Adafruit 2.5W Class D Single Channel Audio Amplifier Board

This super small mono amplifier is 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. It has built in thermal and over-current protection but we could barely tell it got hot. There #39;s even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. The A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully #39;differential #39; - if you don #39;t have differential outputs, simply tie the Audio- pin to ground. The output is #34;Bridge Tied #34; - that means the output pins connect directly to the speaker pins,no connection to ground. The output is a high frequency 250KHz square wave PWM that is then #39;averaged out #39; by the speaker coil - the high frequencies are not heard. Speaker is not included, use any 4 ohm or greater impedance speaker. 1.Output Power: 2.5W at 4, 10% THD, 1.5W at 8, 10% THD, with ` Supply 2.50dB PSRR at 1KHz 3.Filterless design, with ferrite bead + capacitors on output. 4.Fixed 24dB gain, onboard trim potentiometer for adjusting input volume. 5.Thermal and short-circuit/over-current protection 6.Low current draw: 4mA quiescent and 1uA in shutdown mode Link Barang Sejenis yang mungkin anda cari : : https://www.tokopedia.com/rajacell/pam8403-2x3w-stereo-power-amplifier-mini-audio-ampli-2-x-3watt ✪ https://www.tokopedia.com/rajacell/pam8403-2x3w-digital-power-amplifier-module-pcb-merah ✪ https://www.tokopedia.com/rajacell/new-pam8403-audio-amplifier-2-x-3watt-stereo-5v-dengan-port-micro-usb ✪ https://www.tokopedia.com/rajacell/pam8403-stereo-power-amplifier-2x3w-potensiometer-volume ✪ https://www.tokopedia.com/rajacell/pam8610-2x15w-digital-stereo-power-amplifier-mini-2-x-15watt ✪ https://www.tokopedia.com/rajacell/digital-amplifier-class-d-stereo-2x-15watt-pam8610-volume-control-hitam
