Gamma Correction Channels: 10, 6
Integrated V Buffer
The BUFxx702 are a series of multi-channel buffers
targeted towards gamma correction in high-resolution
LCD panels. The number of gamma correction
channels required depends on a variety of factors and
differs greatly from design to design. Therefore, various
channel options are offered. For additional space and

Large Capacitive Load Drive Capability
Rail-to-Rail Output
The various buffers within the BUFxx702 are carefully
matched to the voltage I/O requirements for the gamma
correction application. Each buffer is capable of driving
heavy capacitive loads and offers fast load current

See typical characteristic curves for detail.
The BUF07702 and BUF11702 is available in the
TSSOP-PowerPAD package for dramatically
increased power dissipation capability. This way, a
large number of channels can be handled safely in one
package.

A flow-through pinout has been adopted to allow simple
PCB routing and maintain the cost-effectiveness of this
solution. All inputs and outputs of the BUFxx702
incorporate internal ESD protection circuits that prevent
functional failures at voltages up to 4kV (HBM) as
tested under MIL-STD-883C Method 3015.
The BUF07702 is not recommended for new designs. Informa-
tion is provided for reference only. For new designs, the pin-com-
patible BUF07703 is recommended; more information can be
found at www.ti.com.
