CXLC8980由14+1通道缓冲组成,以满足薄膜晶体管液晶显示器(TFT-LCD)的需要。该装置包括一个Vcom缓冲器和14个gamma缓冲器,并通过I2 C接口编程。它包含两个寄存器组,可以存储两组不同的gamma参考值。每个缓冲器能够驱动重电容负载并提供大电流负载(Vcom:100mA,Gammas:25mA)。
电源工作范围:6.5V至18V
14+1频道:
---14通道轨对轨可编程缓冲器
每个通道10位分辨率
每个通道的25毫安输出电流
---1通道轨对轨Vcom缓冲器:
7位可调输出
输出电流±100mA
140mA输出短路电流
20V/μs转换率
2线I2 C从模式接口
使用一个控制管脚使能将数据存储到非易失性存储器(NVM)
非易失性存储器(NVM)存储设置(至少100次重新写入)
