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

> 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).
