The ADD8504, ADD8505, and ADD8506 are 4-, 5-, and
6-channel LCD gamma reference buffers designed to drive
column driver gamma inputs in line inversion panels. Each
buffer channel has an A/B input to select between two gamma
voltage curves. These buffer channels drive the resistor ladders
of LCD column drivers for gamma correction. The ADD8504/
ADD8505/ADD8506 outputs have high slew rates and output
drives that increase the stability of the reference ladder resulting
in optimal gray scale and visual performance.

ADD8504/ADD8505/ADD8506
APPLICATIONS INFORMATION
The ADD8504/ADD8505/ADD8506 have CMOS buffers with
A/B inputs 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 the use of
a very large resistor ladder to save supply current.
Power supply pins on the ADD8505 and ADD8506 have
multiple ground (GND) and supply (VCC) connections.
Because of the high peak currents that these buffers deliver, it
is recommended that all GND and VCC pins be connected and
suitably bypassed.
The buffer outputs are designed to drive resistive or capacitive
loads. Therefore, to attain the best display performance, do not
use resistors in series with these outputs. Outputs have high
slew rates and 6 μs settling times. Each output delivers a mini-
mum of 120 mA, ensuring a fast response to varying loads.
