TSSOP packages
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.
