8.2.3 Application Curve

An example output response of a bidirectional configuration is shown in Figure 8-2. With the REF pin connected to a reference voltage, 2.5 V in this case, the output voltage is biased upwards by this reference level. The output rises above the reference voltage for positive differential input signals and falls below the reference voltage for negative differential input signals.
