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. The ADD8506 is also offered

in a leaded TSSOP.
