TK15327
TOTAL HARMONIC DISTORTION (FIGURE 4)
Use the lower distortion oscillator for this measurement
because distortion of the TK15327 is very low.
1) Connect V
to Pin 5, Pin 8 is low level or open.
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, reverse conditions at Pin 5 and Pin 8.
6) Input the same sine wave to Pin 2.
7) Measure in the same way. This value is the distortion
of 1-Bch.
VOLTAGE GAIN (FIGURE 5)
This is the output level against input level.
1) Connect V
to Pin 5, Pin 8 is low level or open.
2) Connect AC volt meters to Pin 4 and Pin 3.
(Using the same type meter is best)
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)
V1<V2 + Gain, V1>V2 - Gain
This value is the voltage gain of 1-Ach.
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.
This value is the voltage gain of 1-Bch.
CONTROL INPUT IMPEDANCE (FIGURE 3)
This is the input resistance of control terminals.
1) Measure the inflow current from V
CC
to Pin 5.
2) Calculate:
IMP = V
/ Inflow Current
This resistancde is the input impedance.
