4-Channel, Muxed Input Line Inversion LCD Gamma Buffer
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 40C to +105C 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.
