四通道、I²C、可控制裕量的IDAC，具有三路电源跟踪

DS4426集成了4路I²C可调节、电流输出DAC，这些DAC可吸入或源出电流，并通过外部电阻设置每路输出的满量程范围。每路DAC输出可通过I²C接口设置127个吸入电流和127个源出电流等级。采用指定的控制输入，还可为三路通道提供电源跟踪功能。当电源跟踪完成后，电流输出默认为零。两个地址引脚允许在同一个I²C总线上挂接最多4个DS4426。 • 四路电流输出DAC \n• 50µA至200µA可调节满量程范围 \n• 每路输出的吸入、源出电流具备127个设定值\n• 电源跟踪 \n• 电源排序 \n• 斜坡上升和斜坡下降跟踪控制 \n• 支持比例跟踪 \n• +2.7V至+5.5V工作电压 \n• I²C兼容串行接口 \n• 两个地址输入引脚允许在同一个I²C总线上挂接最多4个器件 \n• 无铅、28引脚TQFN封装(4mm x 4mm)，带裸焊盘 \n• 工业级温度范围：-40°C至+85°C;
