Guitar amplifier & other music instrument amplifier

Block diagram


Our integrated circuits and reference designs help you develop high-quality class-D guitar amplifier and other music instrument amplifiers with twice the efficiency of class-AB amplifiers in cost-conscientious designs.

Design requirements:

Guitar amplifier and other music instrument amplifier designs often require:

  • The ability to select different sound effects with connectivity and LCD screens.
  • The capture of line and microphone input signals without distortion.
  • Inductance-to-digital converters applicable to selecting preset effects on the newest guitar amps.
  • Support of guitar playback effects such as reverb, delay and flanger.
