LMC6009
9 Channel Buffer Amplifier for TFT-LCD
General Description
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.
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.
The LMC6009 is available in 48-pin surface mount TSSOP.
