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.
The ADD8504/ADD8505/ADD8506 are specified over the
−40°C to +105°C temperature range. They are available, respec-
tively, in 16-, 20-, and 24-lead thin shrink small outline (TSSOP),
surface-mount, Pb-free packages.
