SEPARATION (FIGURE 9)
This is the cross talk between 1ch and 2ch.
1) Connect either Pin 5 or Pin 8 to V
CC
. One side pin is low
level or open.
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
and a resistance.
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:
SEP = 20 Log (V6 / V5)
This value is the separation to 2ch from 1ch.
TEST CIRCUITS AND METHODS (CONT.)
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
CC
to Pin 5, Pin 8 is in the open condition or low
level.
2) Connect a DC volt meter to Pin 3 and measure.
This value is the terminal voltage of 1-Ach.
3) Next, reverse conditions at Pin 5 and Pin 8.
4) Measure in the same way.
This value is the terminal voltage of 1-Bch.

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.
Vcent = | (1 - Ach value) - (1 - Bch value) |
This value is the voltage difference of 1ch.
