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
μ
s typically.
APPLICATION
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 R
, 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 V
CC
/2 V.

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.).
