AD8644ARUZ

AD8644 is a quad channel, rail-to-rail amplifier optimized for LCD monitor applications. It is processed using the Analog Devices, Inc. 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 or densely packed designs. In addition, the rail-to-rail output swing provides greater dynamic range and control than standard video amplifiers provide. It is widely used in application such as LCD gamma and VCOM drivers, modems, portable instrumentation, direct access arrangement etc.
