The AD8644ARZ is a rail-to-rail quad Operational Amplifier optimized for LCD monitor applications. It is processed using the high voltage, extra fast complementary bipolar (HV XFCB) process. This proprietary process includes trench-isolated transistors that lower internal parasitic capacitance, which improves gain bandwidth, phase margin and capacitive load drive. The low supply current of 800μA (typical) per amplifier is critical for portable designs. In addition, the rail-to-rail output swing provides greater dynamic range and control than standard video amplifiers provide. This product operates from supplies of 5V to as high as 18V. The unique combination of an output drive of 70mA, high slew rates and high capacitive drive capability makes the AD8644 an ideal choice for LCD applications.
