GENERAL DESCRIPTION

The AD8565, AD8566, and AD8567 are low-cost single supply
rail-to-rail input and output operational amplifiers optimized for
LCD monitor applications. They are built on an advanced high­voltage CBCMOS process. The AD8565 contains a single
amplifier, the AD8566 has two amplifiers, and the AD8567 has
four amplifiers.

These LCD op amps have high slew rates, 35 mA continuous
output drive, 250 mA peak output drive, and high capacitive load
drive capability. They have wide supply range and offset voltages
below 10 mV. The AD8565, AD8566, and AD8567 are ideal for
LCD grayscale reference buffer and V

COM

applications.

The AD8565, AD8566, and AD8567 are specified over the –40°C
to +85°C temperature range. The AD8565 single is available in a
5-lead SC70 package. The AD8566 dual is available in an 8-lead
MSOP package. The AD8567 quad is available in a 14-lead
TSSOP package and a 16-lead lead frame Chip Scale Package.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent 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.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD8565/AD8566/AD8567 features proprietary ESD protection circuitry, permanent damage
may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
