8.2.1.3 Application Curve

An example output response of a unidirectional configuration is shown in Figure 8-2. With the REF pin connected directly to ground, the output voltage is biased to this zero output level. The output rises above the reference voltage for positive differential input signals but cannot fall below the reference voltage for negative differential input signals because of the grounded reference voltage.
