OUT2M Driver CH2 negative output

Note) The positive or negative polarity of driver outputs is determined by the input polarity.

CH1: When the inverted AMP is used for the input stage OP-AMP, the H input results in L at the

negative output pin and H at the positive output pin.

CH2/CH3: Applying the signal H to the input pin results in L at the negative output pin and H at

the positive output pin.
