Note 1: The KEY input equivalent circuit is shown to the right.

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

Input Key

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: Power dissipation is 350 mW when mounted as recommended. Derate at 3.0 mW/°C for operation above

25°C.
