CXLC8975 CXLC8976由18+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。这个装置包括一个Vcom缓冲器和18个伽马缓冲器。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:30mA)
电源工作范围:6.5V至19.5V
18+1频道:
18个缓冲器,每个连续输出电流为±30mA(最大值)
1个Vcom缓冲器,连续输出电流为±100mA(最大值);VDD=10V时的电源电流:14mA(典型值)
单位增益Vcom缓冲器,能够驱动大电容负载,输入共模范围超出轨道
轨对轨输出电压摆动
峰值输出电流:
缓冲区:120mA
Vcom缓冲器:±300毫安
