9 Channel Buffer Amplifier for TFT-LCD

General Description

Features

n Number of inputs

The LMC6009 is a CMOS integrated circuit that buffers 9 ref-

erence voltages for gamma correction in a Thin Film Transis-

tor Liquid Crystal Display (TFT-LCD). Guaranteed to operate

at both 3.3V and 5V supplies, this integrated circuit contains

nine, independent unity gain buffers that can source 130 mA

into a capacitive load without oscillation.

3 µs

The LMC6009 is useful for buffering gamma voltages into

column drivers that employ the resistor-divider architecture.

High output current capability and fast settling characteristics

of this device improve display quality by minimizing rise time

errors at the outputs of the column driver. The integration of

nine buffers and a multiplexer eliminates the need for dis-

crete buffers and a separate multiplexer (MUX) chip on the

panel.

Applications

n VGA/SVGA TFT-LCD drive circuits

n Electronic Notebooks

n Electronic Games

The LMC6009 is available in 48-pin surface mount TSSOP.

n Personal Communication Devices

n Personal Digital Assistants (PDA)
