LTC1663 具二线式接口的 10 位轨至轨微功率 DAC
LTC®1663 是一款 10 位电压输出 DAC，该器件具有真正的缓冲轨至轨输出电压能力。它采用一个电压范围为 2.7V 至 5.5V 的单工作电源。用于该 DAC 的基准可以在电源电压或一个内部带隙基准之间进行选择。当选择内部带隙基准时，将把全标度输出电压范围设定在 2.5V。而当选择电源作为基准时，输出电压范围将被设定在电源电压。
该器件具有一个与 SMBus 相兼容的简单二线式串行接口，允许在多个设备之间进行通信。对内部数据寄存器进行了双重缓冲，以便立刻对多个设备进行同时更新。该 DAC 可被置于低电流断电模式，以供那些希望节省功率的系统之用。
上电复位可确保 DAC 输出在最初加电时处于 0V，而且所有的内部寄存器均被清零。
