Input Key
Note 1: The KEY input equivalent circuit is shown in Figure A.
When the control pin is open, it is outputted low level. The TK15328 is controlled by two
values,
and the function table is described in the block diagram.
Note 2: The specification means a value as measurement-input terminal connects to ground
through a capacitor.
Note 3: ISO is a cross talk between A channel and B channel, SEP is a cross talk between 1
channel and 2 channel. The specification means a value as measurement-input terminal
connects to ground through 10 k
resistor and capacitor.
Note 4: Input equivalent circuit is shown in Figure B. The standard application of TK15328M is
the direct connecting with the GND bias. When connecting a capacitor, then to supply a
bias voltage from GND to input be any resistor is necessary.
Note 5: Power dissipation is 350 mW when mounted as recommended. Derate at 3.0 mW/
°
C
for operation above 25
°
C.
