GENERAL DESCRIPTION
The AD8614 (single) and AD8644 (quad) are single-supply,
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.
These products operate from supplies of 5 V to as high as 18 V.
The unique combination of an output drive of 70 mA, high
slew rates, and high capacitive drive capability makes the
AD8614/AD8644 an ideal choice for LCD applications.
The AD8614 and AD8644 are specified over the temperature
range of –20°C to +85°C. They are available in 5-lead SOT-23,
14-lead TSSOP, and 14-lead SOIC surface-mount packages in
tape and reel.
