5.5 MHz bandwidth, rail-to-rail amplifiers optimized for LCD
monitor applications.
They are 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 800 μA (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. V+ 4 AD8644 TOP VIEW …
