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'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 'differential' - if you don't 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 PWM that is then 'averaged out' 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 4ω, 10% THD, 1.5W at 8ω, 10% THD, with 5.5V 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.Find many great new \u0026amp; used options and get the best deals for PAM8302 2.5W D-Class Audio Power Mono Amplifier Module Development Board 5.5V at the best online prices at Order2india Shopping!
