External Analog Filter Circuit
The 2nd order LPF (fc=111.8kHz, Q=0.714) is implemented on the board. When the further attenuation of the out-band noise is needed, some additional LPF is required. Analog signal is output through BNC connectors on the board. And the output level of the AK4384 is 5.68Vpp@5V.
