DC Splitter

Introduction

 This project came about because of the new EU recommendations to have energy-efficient 'wall wart' supplies. These are typically SMPS and thus only have DC output, so there is a need to obtain a split supply for powering high-quality op-amp circuits. The board features the option to fit a LED to give indication when power is on. The input is filtered to make sure any residual noise from the SMPS is kept out of the audio. The input also features reverse polarity protection.
