• Description: Audio Analog Switch
• Manufacturer: TOKO

V CC
I/O TERMINAL VOLTAGE (FIGURE 10)
This is the DC voltage of input and output.
Because the input and the output are nearly equal, only the
output is measured.
1) Connect V
2) Connect a DC volt meter to Pin 3 and measure.
3) Next, reverse conditions at Pin 5 and Pin 8.
4) Measure in the same way.

SEPARATION (FIGURE 9)
This is the cross talk between 1ch and 2ch.
1) Connect either Pin 5 or Pin 8 to V
2) Connect AC volt meters to Pin 4 (or Pin 2) and Pin 10.
3) Connect Pin 9 and Pin 11 to GND through capacitors
4) Input a sine wave (10 kHz, 1 Vrms) to Pin 2 and Pin 4.
5) Measure the level of Pin 4 and name this V5.
6) Measure the level of Pin 10 and name this V6.
7) Calculate:
level.
This value is the terminal voltage of 1-Ach.
This value is the terminal voltage of 1-Bch.

and a resistance.
This value is the separation to 2ch from 1ch.

OUTPUT TERMINAL DIFFERENCE
This is the DC output voltage difference between Ach and
Bch. This is calculated by using values measured at the
I/O Terminal Voltage.
This value is the voltage difference of 1ch.
