## Overview

The Adafruit Stereo 2.8W Class D Audio Amplifier (TPA2016) is a compact, highly efficient stereo amplifier delivering up to 2.8W per channel at 4Ω with 10% THD. Featuring an I2C interface for precise gain and AGC control, it ensures distortion-free audio with smart automatic gain adjustments. Its Class D design offers 89% efficiency, making it perfect for portable and battery-powered projects, while built-in protections keep it running cool and reliable.

## Description

A mini cl D with AGC and I2C control? Yes please! This incredibly small stereo amplifier is surprisingly powerful. It is able to deliver 2 x 2.8W channels into 4 ohm impedance speakers (@ 10% THD) and it has a i2c control interface as well as an AGC (automatic gain control) system to keep your audio from clipping or distorting. If you don't want to use I2C to control it, it does start up on with 6dB gain by default and the AGC set up for most music playing. We do suggest using it with a microcontroller to configure it, however, since its quite powerful. Settings are not stored in the chip, so you'll need to adjust any gain & AGC amplification settings every time the amp is powered up. Inside the miniature chip is a cl D controller, able to run from 2.7V-5.5VDC. Since the amp is a cl D, it's incredibly efficient (89% efficient when driving an 8Ω speaker at 1.5 Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell if it got hot. This board is a welcome upgrade to basic "LM386" amps!

## Features

- Output Power: 2.8W at 4Ω, 10% THD, 1.7W at 8Ω, 10% THD, with 5V Supply
- PSRR: 80 dB, 5ms startup time
- Designed for use without an output filter, when wires are kept at under 2"-4" long
- I2C interface pins for setting gain, AGC configuration parameters, etc. See our tutorial for more details
- Selectable gain from -28dB to 30dB
