Figure 24. Gamma Buffer Drive Capability
APPLICATIONS WITH >10 GAMMA CHANNELS
When a greater number of gamma correction channels
are required, two or more BUFxx704 devices can be
used in parallel, as shown in Figure 25. This capability
provides a cost-effective way of creating more refer-
ence voltages over the use of quad-channel op amps or
buffers. The suggested configuration in Figure 25
simplifies layout. The various different channel versions
provide a high degree of flexibility and also minimize
total cost and space.

MULTIPLE V
COM
CHANNELS
In some LCD panels, more than one V
COM
driver is
required for best panel performance. Figure 26 uses
three BUF07704s to create a total of 18 gamma-correc-
tion and three V
COM
channels. This solution saves
considerable space and cost over the more convention-
al approach of using five or six quad-channel buffers or
op amps.
