ADD8504开发板套件编程器的评估演示板及套件规格书PDF中文资料

ADD8504属于开发板套件编程器的评估演示板及套件。由亚德诺半导体技术有限公司制造生产的ADD8504评估和演示板及套件该系列产品提供了一种方便的方法，在经过验证的实施环境中评估某些重点器件的性能或特性。评估方法通常有完善的文档说明，并且视乎具体情况由评估软件提供支持。产品通常由印刷电路板组成，板上已装有重点器件以及必要或有用的支持元器件，另外也可能包括其他组件，例如电缆或电源。对于数量特别多或类别独特的器件类别(如 ADC、DAC 和开关模式电源)，评估平台可组合为一个单独的产品系列。

GENERAL DESCRIPTION

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.
