TEST CIRCUITS AND METHODS (CONT.)
CONTROL LOW/HIGH LEVEL (FIGURE 2)
VCC
This level is to measure the threshold level.
1) Input, the VCC to Pin 1. (This condition is the same with
other measurements, omitted from the next for simplicity)
2) Input to Pin 4 with sine wave (f = 1 kHz, VIN = 1 Vrms).
3) Connect an oscilloscope to Pin 3.
4) Elevate the control voltage from 0 V gradually, until the
sine wave appears at the oscilloscope. This voltage is
the threshold level when the wave appears.

CONTROL OUTFLOW/INFLOW CURRENT (FIGURE 3)
This current means the maximum current with the control.
1) Measure the current from Pin 5 to GND. This current is
the outflow current.
2) Next, measure the current from VCC to Pin 5. This
current is the inflow current.
TOTAL HARMONIC DISTORTION (FIGURE 4)
Use the lower distortion oscillator for this measurement
because distortion of the TK15323 is very low.
1) Pin 5 is in the open condition, or high level.
2) Connect a distortion analyzer to Pin 3.
3) Input the sine wave (1 kHz, 1 Vrms) to Pin 4.
4) Measure the distortion of Pin 3. This value is the
distortion of 1-Ach.
5) Next connect Pin 5 to the GND, or low level.
6) Input the same sine wave to Pin 2.
7) Measure in the same way. This value is the distortion
of 1-Bch.
