TK15325
KEY INPUT CIRCUIT
1ch and 2ch is separate action by each control keys. Figure
11 is an equivalence circuit of key input. When terminal of
key is the open, is outputting high level (about 1.4 V), and
then Ach input signal is outputted. The channel at TK15325M
can be changed by low level. When a control terminal is
operated to low function , sometimes may flows out
maximum values about 30
μ
A as current from the terminal.
For this reason, use a resistance which does not exceed
0.8 V value when attaching a resistance to the outside and
make low 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 the
inputs and outputs of the TK15325M. For characteristics of
distortion and dynamic range versus R
, refer to the graphs
in the Typical Performance Characteristics. The TK15325M
can be used at the capacitor coupling too, but then the bias
supply is necessary from outside.

CROSS TALK (ISOLATION AND SEPARATION)
Figure 14 is an example of a layout pattern. As the
TK15325M 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)
