ADD8506-EVAL: 6通道、多路输入行反转LCD伽玛缓冲器
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.
ADD8504,ADD8505与ADD8506分别是4通道、5通道、6通道LCD伽玛参考缓冲器,用于驱动行反转面板中列驱动伽玛输入信号。缓冲器的每个通道都拥有A/B输入端口,在两个伽玛电压曲线中进行选择。为了实现伽玛校正,这些缓冲器通道驱动LCD列驱动电路的梯形电阻。ADD8504/ADD8505/ADD8506输出具有高摆率和高驱动能力,可以提高基准梯形的稳定性,实现最佳灰度等级与视觉性能。
ADD8504/ADD8505/ADD8506的工作温度范围是：-40°C～+105°C。它们分别采用16引脚、20引脚和24引脚无铅超薄小外形(TSSOP)、表面安装封装。ADD8506还采用有引线的TSSOP封装
