They are processed using Analog Devices high voltage, high speed, complementary bipolar process--HV XFCB. 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 A (typ) 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.
