DESCRIPTION
The BUFxx703 are a series of multi-channel buffers
targeted towards gamma correction in high-resolution
liquid crystal display (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 cost savings, a
VCOM channel with higher current drive capability is
integrated in the BUF07703 and BUF05703.
A flow-through pinout has been adopted to allow
simple printed circuit board (PCB) routing and
maintain the cost-effectiveness of this solution. All
inputs and outputs of the BUFxx703 incorporate
internal ESD protection circuits that prevent functional
failures at voltages up to 4kV HBM and 1.5kV CDM.
The various buffers within the BUFxx703 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 switching. The VCOM channel has increased
output drive of > 100mA and can handle even larger
capacitive loads.
The BUF07703 is available in the HTSSOP
PowerPAD™ package for dramatically increased
power dissipation capability. The BUF06703 and
BUF05703 are available in standard TSSOP-16 and
TSSOP-14 packages.
