Application note
It is recommended not to leave the Ref pin (pin 11) floating: if not used with an external
voltage reference, it is better to connect an external capacitor (of at least 10 nF) between
this pin and ground.
This capacitor filters the voltage reference against voltage spikes that can be generated by
the commutation of the output stages.
This is very common using capacitive loads: in fact, the initial transient of such loads
behaves like a short circuit, so the current flowing through the outputs presents very high
spikes.
Moreover, if the device is used as a line receiver. (i.e. the input signals can go below ground)
it is required not to leave the Ref pin (pin 11) floating: in this case, the pin can be connected
to ground or to a fixed external voltage reference.
