APPLICATION CIRCUIT AND NOTE
To further suppress residual noise, we suggest placing an additional low pass filter after the analog
output of PT8211. Please refer to the circuit diagram below. This is a simple second-order analog post
filter. If low noise output is very important for your circuit design we suggest using a regulated power
supply.
