GENERAL DESCRIPTION

Figure 2. 14-Lead TSSOP

(RU-14)

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.
