GENERAL DESCRIPTION
The ADD8506 has 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 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 ADD8506 is specified over the −40°C to +105°C
temperature range. It is available in a 24-lead thin shrink small
outline (TSSOP), surface-mount, Pb-free package.
