Headphone amplifiers usually require positive and negative voltages. In this reference design, both voltages are generated from a single input voltage with an integrated split-rail charge-pump converter. It provides small solution size with five capacitors and four resistors.
- Small solution size
- Low distortion
- Small BOM - only nine external components
- Adjustable output voltage
- Tested circuit design; test report and design files are included
