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 8 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.

Comes with a fully assembled and tested breakout board. We also
include header to plug it into a breadboard and a 3.5mm screw-terminal
blocks so you can easily attach/detach your speaker. You will be ready
to rock in 15 minutes! Speaker is not included, use any 4 ohm or
greater impedance speaker.
