THE AD8383, IN THE APPLICATIONS
CIRCUIT SHOWN, TYPICALLY PRODUCES
EXTERNAL VBIAS GENERATION
In systems that require improved brightness resolution and
higher accuracy, the V1 and V2 inputs, connected to external
voltage references, provide the necessary VBIAS while allowing
the full code range to be used for gamma correction.
A SYMMETRICAL OUTPUT AT 85°C WHEN
ITS SUPPLY, (V+) – (V–), IS AT 7.2V.

V1 sets the white drive voltage while INV = LOW and V2 sets
the white drive voltage while INV = HIGH. V1 and V2 are
defined as
V1 = VCOM – VBIAS
V2 = VCOM + VBIAS

To ensure a symmetrical ac driving voltage, the difference
between V2 and VCOM must be equal to the difference
between VCOM and V1 .
