EC5575
14+1 Channel Voltage Buffers for TFT LCD
FEATURES
• Wide supply voltage range 6.5V ~ 18V
• Rail-to-rail output swing (The highest two
stage & lowest two stage)
• High slew rate 1V/µs
• GBWP 1 MHz
• 2 MHz -3dB Bandwidth
• Large Vcom Drive Current: ±100mA(Max)
• Ultra-small Package TQFP-48
APPLICATIONS
• TFT-LCD Reference Driver
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.
