• Description: Audio Analog Switch
• Manufacturer: TOKO

VOLTAGE GAIN (FIGURE 5)
This is the output level against input level.
1) Connect V
2) Connect AC volt meters to Pin 4 and Pin 3.
3) Input a sine wave (f = max. 20 kHz, 1 Vrms) to Pin 4.
4) Measure the level of Pin 4 and name this V1.
5) Measure the level of Pin 3 and name this V2.
6) Calculate Gain = 20 Log (( |V2 - V1| )/V1)
7) Next, reverse conditions at Pin 5 and Pin 8.
8) Input the same sine wave to Pin 2.
9) Measure and calculate in the same way.
