Version 3 is the newest version of our best selling Mono Amplifier Kit that can be used with any personal stereo equipment, including MP3 players, making it an ideal kit choice for an amplifier case design project.

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.
