Note 1: The KEY input equivalent circuit is shown in Figure A.
1 channel and 2 channel is the separate action by 1Key pin and 2 key pin. When the control pin is
open, it is outputted high level (about 1.4 V). Then the A channel input signal is outputted. The
change is carried out at low level.
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 termianl connects to ground
through 10 kΩ resistor and capacitor.
Note 4: Input equivalent circuit is shown in Figure B. The standard application of TK15325M is the direct
connecting. When connecting a capacitor, supplying a bias voltage from outside is unnecessary.
Note 5: Power dissipation is 350 mW when mounted as recommended. Derate at 3.0 mW/°C for operation
above 25°C.
