DESCRIPTION
The BUF11705 is a multi-channel buffer targeted
towards gamma correction in high-resolution LCD
panels. It is pin-compatible with the existing BUF11702
and BUF11704 and operates at higher supply voltages
up to 22 V (24 V absolute max). The higher supply
voltage enables faster response times and brighter
images in large-screen LCD panels. This is especially
important in LCD TV applications.
The BUF11705 offers 10 gamma channels. For
additional space and cost savings, a VCOM channel with
> 100 mA drive capability is integrated into the
BUF11705.
The BUF11705 is available in the TSSOP-28
PowerPAD package for dramatically increased power
dissipation capability. This allows a large number of
channels to be handled safely in one package.
A flow-through pinout has been adopted to allow
simple PCB routing and maintain cost-effectiveness. All
inputs and outputs of the BUF11705 incorporate
internal ESD protection circuits that prevent functional
failures at voltages up to 8 kV (HBM), 2 kV (CDM), and
300 V (MM).
