DS15BR400: Unused Pins

Lindsey Fike

Part Number: DS15BR400

For unused inputs like IN2+/- (pins 13/14) and IN3+/- (pins 15/16).  Can those be left unconnected if not used?

    Hi Lindsey,

    The unused inputs should be tied off as listed below to ensure the outputs remain in a stable state.

    IN+ = 3.3K to VDD

    IN- = 3.3K to GND

    This will ensure 50mV of offset at the input which is enough to keep the output from switching.

    Regards,

    Lee
