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 V_COM channel
with higher current drive capability is integrated in the
BUF07703 and BUF05703.
A flow through pin out has been adopted to allow simple
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 V_COM 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.
