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 high-
voltage 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
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.

... 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 ...

... AD8565/AD8566/AD8567 APPLICATIONS Theory of Operation The AD856x family is designed to drive large capacitive loads in LCD applications. It has high output current drive, rail-to-rail input/output operation and is powered from a single 16 V supply also intended for other applications where low distortion and high output current drive are needed. ...

... It can instantaneously source/sink greater than 250 mA of current. At unity gain, it can drive 1 µF without compensation. This makes the AD856x ideal for LCD V To evaluate the performance of the AD856x family, a test circuit was developed to simulate the V LCD panel AD8565/AD8566/AD8567 ...
