CXD2475TQ
Reference Voltage and Driver IC for LCD
Description
The CXD2475TQ is suitable IC for applying reference
voltage for gamma correction which is necessary for
TFT liquid crystal display. This IC has a built-in 9
channels of rail-to-rail buffer circuit which enables 2-
input switch and a common driver circuit.
