Professional microphones & wireless systems

Block diagram

Overview

Our integrated circuits and reference designs will help you develop professional microphones and wireless systems in a small form factor. These designs utilize audio data converters and low power digital signal processors (DSPs) capable of sampling audio signals up to 192 kHz.

Design requirements

Professional microphones and wireless systems often require:

  • Excellent audio quality with low noise and low total harmonic distortion.
  • Radio frequency (RF) synthesizers which support direct digital frequency-shift keying (FSK) modulation.
  • Ultra-low power consumption for extensive transmitter battery life.
