1: The above condition tests the dynamic range measurement for channel A.
2: SW5 is for residual noise measurement.
3: SW8 is for cross talk measurement.
SUPPLY CURRENT (FIGURE 1)
This current is a consumption current with a nonloading
condition.
1) Bias supply to Pin 1 and Pin 3. (This condition is the
same with the other measurements too, omits from
next).
2) Measure the inflow current to Pin 6 from VCC.
This current is the supply current.

3) Connect an oscilloscope to Pin 2.
4) Elevate the Pin 4 voltage from 0 V gradually, until the
sine wave appears at the oscilloscope. This voltage is
the threshold level when the wave appears.

CONTROL LOW/HIGH LEVEL (FIGURE 2)
This level is to measure the threshold level.
1) Input, the V
to Pin 6. (This condition is the same with
the other measurements, omitted from the next for
simplicity.)
2) Input to Pin 1 with sine wave (1 kHz, 1 Vrms).
KEY INPUT CURRENT (FIGURE 3)
This current means the outflow current with the control
terminal.
1) Measure the current to GND from Pin 4. This current is
the outflow current.
