The hysteresis control may also be connected to ground (GND), which
produces another set of switching levels. This connection is shown in figure
B-4. If the HYSTR terminal is shorted to GND the nominal switching point is
1.6V with ±5mV of hysteresis.
To measure AC signals super-imposed on a DC value, the input may be AC
coupled by simply placing a capacitor in series with the +IN terminal. The
