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 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 mar-
gin and capacitive load drive. The low supply current of 800
μ
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.
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.
