SC9200A - DTMF GENERATORS

General Description

The SC9200 tone generators are designed for µC interfaces.

They can be instructed by a µC to generate 16 dual tones and 8 single tones from the DTMF pin.

Key Features

  • Operating voltage: 2.0V~5.5V.
  • Serial mode for the SC9200A/AS.
  • Serial/parallel mode for the SC9200B/BS.
  • Low standby current.
  • Low total harmonic distortion.
  • 3.58MHz crystal or ceramic resonator.
