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. Figure 1.
