The AN8001FHK is a 64-gradation LCD grading voltage generation IC with a high-precision reference voltage source (1.23V), a wide dynamic range of buffer amplifiers, and a large COM-amplifier drive current (±100 mA (max.)).
The Panasonic AN8001FHK is a gradation voltage generation IC specifically designed for 64-gradation liquid crystal displays (LCDs). It integrates a high-precision 1.23 V reference voltage circuit, ten gradation output buffer amplifier circuits, and a COM amplifier circuit to provide stable voltage generation for LCD panels.
Key features include a wide dynamic range for buffer amplifiers, allowing output from VCC - 0.2 V to GND + 0.2 V, and a large COM-amplifier drive current of up to 100 mA. The device is housed in a TQFP048 package and operates within an ambient temperature range of 0 to +70 °C.
