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.
