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) Measure the inflow current to Pin 6 from V
CC
. This
current is the supply current.
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 a sine wave (1 kHz, 1 Vrms).
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.
KEY INPUT IMPEDANCE (FIGURE 3)
This impedance means the base resistance of the input
transistor (see terminal circuit on page 8).
1) Remove V
of Pin 6.
2) Measure the resistance value by measuring instrument.
(e.g., multimeter etc.)
