FEATURES

DESCRIPTION

The BUFxx704 are a series of multi-channel buffers

targeted towards gamma correction in high-resolution

LCD panels. They are pin-compatible with the existing

BUFxx702 and BUFxx703 family and operate at higher

supply voltages up to 18 V (19 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.

Wide Supply Range: 4.5 V to 18 V

Gamma Correction Channels: 10, 6, and 4

The number of gamma correction channels required

depends on a variety of factors and differs greatly from

design to design. Therefore, 10, 6, and 4 channel

options are offered. For additional space and cost

is integrated into the BUF11704, BUF07704, and

BUF05704.

Specified for −25°C to +85°C

The BUF11704, BUF07704, BUF06704, and

BUF05704 are available in the TSSOP-28, TSSOP-20,

TSSOP-16, and TSSOP-14 PowerPAD packages for

dramatically increased power dissipation capability.

This way, a large number of channels can be handled

safely in one package.

Gamma 1

BUFxx704

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 BUFxx704

incorporate internal ESD protection circuits that prevent

functional failures at voltages up to 8 kV (HBM), 2 kV

(CDM), and 300 V (MM).
