Applications Information
A 0.1µF decoupling capacitor is required for V
be located either inside the microphone or on the PCB
very close to the VDD pin.
Due to high input impedance, careful consideration
should be taken to remove all flux used during the
reflow soldering process.

A 100Ω resistance is recommended on the clock output
of the device driving the FAN3850T to minimize ringing
and improve signal integrity.
For optimal PSR, route a trace to the VDD pin. Do not
place a V
