18+1 Channel Voltage Buffers for TFT LCD
EC5579
Introduction
General Description
The EC5579 is a 18+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 14 buffer
amplifiers circuits.
The EC5579 is available in a space saving 48-pin
TQFP package, and the operating temperature is
from –20°C to +85°C.
Features
Wide supply voltage range 6.5V ~ 18V
Rail-to-rail output swing (The highest two stage &
lowest two stage)
High slew rate 1V/ s
GBWP 1 MHz
2 MHz -3dB Bandwidth
Large Vcom Drive Current: ±100mA(Max)
Ultra-small Package TQFP-48
Applications
