„ GENERAL DESCRIPTION
The EC5575 is a 14+1 channel voltage
buffers that buffers reference voltage for
gamma correction in a thin film transistor
liquid crystal display (TFT LCD). This
device incorporating a Vcom amplifier
circuits, four rail to rail buffer amplifier
circuits (the highest two stage and lowest
two stage) and 10 buffer amplifiers circuits.
The EC5575 is available in a space saving
48-pin TQFP package, and the operating
temperature is from –20°C to +85°C.
