PAM8302 Mono Amplifier Board Cl D 2.5W Audio Power Amplifiers PAM8302A Sound

Descrtions: This super small mono amplifier is able to deliver up to 2.5 Watts into 4-8 impedance speakers. Inside the miniature ch is a cla 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 - the high frequencies are not heard. Speaker is not included, use any 4 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.Filterle 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 Package Included: 1x PAM8302 Mono Amplifier Board About shping
