DESCRIPTION
The TK15321M is an Analog Switch IC that was developed
for audio frequency. Function is to select one output from
two inputs in a device that includes two circuits, and the
channel can be changed by low level. The TK15321M has
a mono-power supply and the input bias is a built-in type
(VCC / 2 V). Because the distortion is very low, the TK15321M
fits various signals switching. It is best suited for Hi-Fi
devices. Operating voltage is wide, the circuit plan is
simple. The TK15321M is available in a small plastic
surface mount package (SSOP-12).

TOTAL HARMONIC DISTORTION (FIGURE 4)
Use the lower distortion oscillator for this measurement
because distortion of the TK15321 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.

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.

VOLTAGE GAIN (FIGURE 5)
This is the output level against input level.
1) Pin 5 is in the open condition, or high level.
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, connect Pin 5 to the GND, or low level.
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.

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.

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) Pin 5 is in the open condition, or high level.
2) Connect a DC volt meter to Pin 3 and measure.
This value is the terminal voltage of 1-Ach.
3) Next, connect Pin 5 to the GND, or low level.
4) Measure in the same way.
This value is the terminal voltage of 1-Bch.
