You can also select a version of this kit with a power switch and status led.
It uses an NCP2890 audio amplifier IC which is pre-mounted on the underside of the board (see image below) and can output 1.0W of power. The NCP2890 is an audio power amplifier designed for portable communication device applications such as mobile phone applications and PDAs. The IC also features an onboard Pop and Click at startup and closedown Noise Protection Circuit.
The kit is supplied with a pre-built jack cable, an 8ohm 66mm speaker, and a AA battery pack and can run off any voltage from 2.2 to 5.5 Volts (Absolute Maximum 6V). For a full list of parts, see the Contents section below.
Previous versions of this amp included a PP3 power connection and were designed to operate around 9V, V3.0 has been designed for use with 2 x AA batteries. There are several advantages to using AA batteries over PP3, they include; AA batteries are much cheaper, more readily available and will also last significantly longer than PP3 batteries, anything up to ten times longer.
Note: this kit requires soldering.
