■ Overview

The AN8001FHK is a gradation voltage generation IC for liquid crystal displays and designed for 64-gradation LCDs. It is incorporating an 1.23 V reference voltage circuit, 10 gradation output buffer amplifier circuits, and a COM amplifier circuit.

■ Features

• Incorporating a high precision reference voltage source : 1.23 V (typ.)

• Wide dynamic range of buffer amplifiers and it is possible to provide an output from VCC − 0.2 V (the highest stage) to GND + 0.2 V (the lowest stage).

• Large COM-amplifier drive current : ±100 mA (max.)

■ Applications

• Gradation power supply source for LCDs
