FSA8069 - Audio Jack

General Description

The FSA8069 is an audio jack detection switch for 3.5 mm and 2.5 mm headsets.

Key Features

  • Detection: - Accessory Plug-In - Send / End Key Press - Impedance Detection - Prevents False Detection due to Moisture.
  • VDD: 3.0 V to 4.5 V.
  • VIO: 1.6 V to VDD.
  • THD (MIC): 0.01% Typical.
  • 15 kV Air Gap ESD.
  • Detects 7 Steps of Headset Impedance.
  • Integrates LDO for MIC Bias Circuit.
  • MIC Switch Removes Audio Jack “Pop” and “Click” Caused by MIC Bias.
