GENERAL DESCRIPTION
The AD8565/AD8566/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 a high capacitive
load drive capability. They have a wide supply range and offset
voltages below 10 mV. The AD8565/AD8566/AD8567 are ideal
for LCD grayscale reference buffer and VCOM applications.
The AD8565/AD8566/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 LFCSP package.
The AD8566WARMZ is the automotive grade version.
