Keep the input signal level in the range 0.5V to 3.8V.
Power supply
Direct-coupling output
Output for the signal input to IN3. When connected to earth a protection circuit operates,
and the IC enters power-save mode.
Direct-coupling output
Output for the signal input to IN2. When connected to earth a protection circuit operates,
and the IC enters power-save mode.
Direct-coupling output
Output for the signal input to IN1. When connected to earth a protection circuit operates,
and the IC enters power-save mode.
