数字调节LCD偏置电源

MAX749在2V至6V输入范围内产生负LCD偏置对比电压。满量程输出电压可调节至-100V或更高，并可通过内部数模转换器(DAC)以64个相等步进进行数字调节。只需要七个小型表面贴装元件即可构建完整的电源。也可以使用PWM信号或电位计来调节输出电压。\n\n 独特的限流控制方案降低了电源电流并有效提高了效率，同时高开关频率（高达500kHz）有效减小了外部元件的尺寸。静态电流最大值仅为60µA，并在关断模式下降至15µA以下。关断时，MAX749保留电压设定点，简化了软件控制。MAX749驱动外部P沟道MOSFET或PNP晶体管。 • 输入电压范围：+2.0V至+6.0V\n\n• 灵活控制输出电压：\n• 数字控制\n\n• 电位器调整\n\n• 脉宽调制控制\n\n\n\n\n• 输出电压范围由一个电阻设置\n\n• 低静态电流：60µA（最大值）\n\n• 关断模式下15µA（最大值）\n\n• 小尺寸，8引脚SO和塑料DIP封装;

双路、通用开关电容滤波器

MAX7490/MAX7491由两个相同的低功耗、低电压、宽动态范围、轨到轨、二阶开关电容构建模块组成。两个滤波器部分各自都可以与两到四个外部电阻一起生成所有标准二阶函数：带通、低通、高通和陷波（带阻）。其中三个函数可同时使用。通过级联两个二阶滤波器部分可以组成四阶滤波器。同样，通过级联多个MAX7490/MAX7491可以轻松组成更高阶滤波器。\n\n 提供两种时钟选项：内置时钟（通过使用外部电容实现），或者外部时钟（用于实现更严格的截止频率控制）。时钟与中心频率比为100:1。采样以两倍时钟频率进行，可将截止频率和奈奎斯特频率进一步分离。\n\n MAX7490/MAX • 采用16引脚QSOP封装的双通道二阶滤波器\n\n• 高精度\n• Q精度：±0.2%\n\n• 时钟与中心频率误差：±0.2%\n\n\n\n\n• 轨到轨输入和输出操作\n\n• 单电源供电：+5V (MAX7490)或+3V (MAX7491)\n\n• 内部或外部时钟\n\n• 高通、低通、带通和陷波滤波器\n\n• 时钟与中心频率比为100:1\n\n• 内部采样与中心频率比为200:1\n\n• 中心频率高达40kHz\n\n• 轻松级联以组成多极滤波器\n\n• 低功耗关断：电源电流：< 1µA;
