## Overview

The Adafruit Mono 2.5W Class D Audio Amplifier (PAM8302) is a compact, highly efficient audio amp delivering up to 2.5 watts into 4-8 ohm speakers. Featuring a Class-D controller with over 90% efficiency, built-in thermal and over-current protection, and a user-friendly volume trim potentiometer, it’s ideal for portable and battery-powered audio projects. Its bridge-tied output ensures clean sound by directly driving speakers without ground interference.

## 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% efficient when driving an 8Ω 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. There's 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! 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. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly.

Review: Mono amp - Very good for a mono amp. Fits perfectly to my project as it's size is small.
Review: Excellent, no problems 😊 - Excellent!

## Questions & Answers

**Q: Does this come with instructions on how to connect to the Raspberry Pi?**
A: Hi,No, instructions available online by adafruit.e-s

**Q: How can I wire headphone jack, speaker and Arduino with this amp?**
A: The screw connector is for the speaker.  the connections marked A+ and A- are for the input connections.  I think you need a mono jack plug and the A+ should be connected the main part of the plug and the A- to the edge.
