IC for Other Information Equipment AN8001FHK Gradation voltage generation IC for liquid crystal display n Overview The AN8001FHK is a gradation voltage generation IC for liquid crystal displays and designed for 64-grada- tion LCDs. It is incorporating an 1.23 V reference volt- age circuit, 10 gradation output buffer amplifier circuits, and a COM amplifier circuit. n Features

  • Incorporating a high precision reference voltage source : 1.23 V (typ.)
  • Wide dynamic range of buffer amplifiers and it is pos- sible to provide an output from VCC - 0.2 V (the high- est stage) to GND + 0.2 V (the lowest stage).
  • Large COM-amplifier drive current : –100 mA (max.) n Applications
  • Gradation power supply source for LCDs Unit : mm TQFP048-P-0707B 7.0±0.1 1348 121 9.0±0.2 (1.00) 0.5±0.1 0° to 8° 7.0±0.1 (0.75) (0.75) 0.20±0.05 9.0±0.2 0.50 0.10 M 1.20 max. 0.15±0.05 (1.0)0.10+0.10 –0.05
