GENERAL DESCRIPTION The ADD8506 is a 6-channel LCD gamma reference buffer and output drives that increase the stability of the reference designed to drive column driver gamma inputs in line inversion ladder, resulting in optimal gray scale and visual performance. panels. Each buffer channel has an INAx and an INBx input to The ADD8506 is specified over the 40C to +105C temperature select between two gamma voltage curves. These buffer range. It is available in a surface-mount, Pb-free, 24-lead thin channels drive the resistor ladders of LCD column drivers for shrink small outline package (TSSOP). gamma correction. The ADD8506 outputs have high slew rates Rev. E Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
