The AD8614(single chip) and AD8644(four chip) are single-channel, 5.5 MHz wide-track-to-track amplifiers optimized for LCD applications. They are processed using Analog Devices, Inc. 's high voltage, ultra fast Complementary Bipolar (HV XFCB) process.
The AD8614/AD8644 has a unique combination of 70 mA output drive, high RPM and high capacitance drive capability, making it ideal for LCD applications. The specified temperature ranges for AD8614 and AD8644 are -20°C to +85°C. They are available in 5-pin SOT-23, 14-pin TSSOP and 14-pin SOIC surface-mount packages for tape and reels. The patented process includes a groove-isolated transistor with reduced internal parasitic capacitance, resulting in increased gain bandwidth, phase margin, and capacitive load drive.
Simplified Schematic
The (typical) low supply current of 800 μA per amplifier is essential for a portable or compact package design. In addition, rail-to-rail output swing provides greater dynamic range and control than standard video amplifiers. These products operate at voltages ranging from 5v to up to 18v.
