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.
