DESCRIPTION
The TK15329M is an Analog Switch IC that was developed
for audio frequency. The function is to select one output
from two inputs and has a floating position too. The
channel can be changed by two control levels and the
device includes two circuits. The TK15329M has a
mono-power supply and the input bias is a supply type
from outside. Because the distortion is very low, the
TK15329M fits various signals switching. It is best suited
for Hi-Fi devices. Operating voltage is wide, the circuit
plan is simple. The TK15329M is available in a small
plastic surface mount package (SSOP-12).

VOLTAGE GAIN (FIGURE 5)
MAXIMUM INPUT LEVEL (FIGURE 6)
This is the output level against input level.
1) Connect VCC to Pin 5, Pin 8 is in the open condition or low
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, 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.
This measurement measures at output side.
1) Connect VCC to Pin 5, Pin 8 is low level or open.
2) Connect a distortion analyzer and an AC volt meter to
Pin 3.
3) Input a sine wave (1 kHz) to Pin 4 and elevate the voltage
gradually until the distortion gets to 0.1%.
4) When the distortion amounts to 0.1%, stop elevating and
measure the AC level of Pin 3.
This value is the maximum input level 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 maximum input level of 1-Bch.

APPLICATION INFORMATION
KEY INPUT CIRCUIT
1ch and 2ch is separate action by each control keys. Figure
11 is an equivalence circuit of key input. If two keys are low
level or high level at the same time then the output is floating
condition. (See Terminal DC Voltage and Circuit table on
page 9).

SWITCHING TIME
This time is the signal change response time compared to
the control key input signal. Figure 12 illustrates the timimg
chart. T = 2 µs typically.

CROSS TALK (ISOLATION AND SEPARATION)
Figure 14 is an example of a layout pattern. In the
application of the TK15329M, the following must be
considered. Because of the high impedance at the inputs,
the capacitors can act as antennas to each other. If the
parts are bigger, and the space between the capacitors is
too narrow, then cross talk will increase. Therefore, when
designing the printed circuit pattern, separate the input
capacitors as far as possible and use as small a part as
possible (e.g., surface mount types, etc.).
APPLICATION
Figure 12
Figure 13 illustrates an example of a typical application.
The standard application is to use direct coupling at the
inputs and capacitor coupling at the outputs of the
TK15329M. For characteristics of distortion and dynamic
range versus RL, refer to the graphs in the Typical Perfor-
mance Characteristics. The TK15329M can also be used
with direct coupling, but the characteristics will get worse
(distortion, etc.). If capacitor coupling is desired, then it is
recommended to use built-in type biased circuitry of the
TK15327M. DC input bias voltage of TK15327M is VCC/2 V.
