KEY INPUT CIRCUIT
Figure 11 is an equivalence circuit of key inputs. 1ch and
2ch does at the same time action by two control keys. If two
keys are low level or high level at the same time then the
output is a floating condition.
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 GND
level at the inputs and outputs of the TK15328M. For
characteristics of distortion and dynamic range versus R
L
,
refer to the graphs in the Typical Performance Character-
istics. The TK15328M can be used at the capacitor
coupling too, but then the bias supply is necessary from the
GND level.

CROSS TALK (ISOLATION AND SEPARATION)
Figure 14 is an example of a layout pattern. As the
TK15328M is a direct coupling type, the influence by
applications is not almost. But, if it is coupled at the
capacitor, by high impedance at input, capacitors
acccomplishes the antenna action each other. Then in
case its parts are bigger, and the space between capacitors
is too narrow, cross talk will increase. Therefore, when
designing the print circuit pattern, separate the input
capacitors as far as possible and use smaller parts. (e.g.,
surface mount type)
