Piano, keyboard & synthesizer

Block diagram


Our integrated circuits and reference designs help you create next-generation piano, keyboard and synthesizer designs with outstanding audio performance, vast polyphony and dynamic system controls. Whether designing for a simple 25-key musical instrument digital interface (MIDI) controller or a state-of-the-art 88-key arranger keyboard, we provide the ability to tailor your requirements for cost and performance optimization.

Design requirements

Piano, keyboard and synthesizer designs often require:

  • Low THD+N for piano platforms tailored towards musicians and studio production.
  • High signal-to-noise ratio (SNR) for audio-performance oriented piano platforms.
  • Process key presses with cost-optimized portable piano platforms.
  • Minimal power stage noise within any keyboard platform.
