GENERAL DESCRIPTION
The AD8509 and AD8511 are 9-channel and 11-channel LCD
reference buffers, respectively, designed to drive 64 gray scale
column drivers. Each buffer has an A/B input to select between
two voltages for LCD displays. These buffers drive the resistor
ladders of LCD column drivers for gamma correction. The LCD
drivers have higher slew rates and higher output drive currents
than similar competitive parts. This increases the stability of
the reference ladder, resulting in better gray scale and visual
performance.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
ESD 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 this product 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.

AD8509/AD8511
APPLICATIONS
The AD8509 and AD8511 are CMOS buffers with A/B inputs
that are used to select between two different reference voltages set
up by an external resistor ladder. Input bias currents are orders
of magnitude less than competitive parts. This allows very large
resistor ladders to be used to save supply current. A guaranteed
value of 50 nA is much higher than actual values and is limited
by leakage in the test system.
The AD8509 is a 9-channel buffer and is similar to the LMC6009
in functionality. The AD8511 is an 11-channel buffer similar to
the CL-FP6131. However, the control to select either 9- or
11-channel operation, the EN_11 pin of the CL-FP6131, is not
available on the AD8511. If 9-channel operation is desired, use
the AD8509.
Power supply pins on the AD8509 and AD8511 have multiple
ground and VCC connections. Because of the high peak currents
that these buffers can deliver, it is strongly recommended to
connect all of the ground and VCC pins, and suitably bypass
the VCC pins.
Buffer outputs are designed to drive resistive loads. They are
also stable with capacitive loads, so no resistors should be used
in series with these outputs to attain the best display perform-
ance. Outputs have high slew rates and 6 μs settling times. Each
output can deliver a minimum of 120 mA, assuring fast response
to varying loads.
