●
A connection to +Vs through a 100Ω resistor, together a 1μF capacitor placed from
+Vs-low and GND is possible too.
NL+, INL-, INR+, INR- Input pins. The sign is referred to the input of the differential-to-
singleended amplifier. Because the power stage is an inverting stage, the output of the
amplifier is with opposite sign with respect these pins. For bridge operation, the
connection INL+ must be shorted to the INR- and the connection INL- must be shorted
to INR+
