NOTES
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.DescriptionThe 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 margin and capacitive load drive. The low supply current of 800 m 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.
