TEST CIRCUIT

LINEAR INTEGRATED CIRCUIT

APPLICATION INFORMATION (refer to test circuits)

External Components

1.) Input coupling capacitor(C1)

The recommended value is 10 mF. If smaller vlaues than 10WF are used, low frequency separation will worsens ,

and is larger values are used, POP noise occurs strongly.

2.) Low Pass Filter (C2,C1,R1)

This is the low pass filter fr the PLL, which is determined the capture range and THD at low frequency.

3.) VCO network (C4,R2,R7)

The VCO free running frequency is adjusted by connecting a frequency counter to monitor the 38kHz output of

Pin6.

4.) Decoder output (Pin8,9)

These components provide Right and Left channel output load circuits. The recommended circuits as follows:
