LTC®2664 是一个 4 通道、16 位 / 12 位、±10V 数模转换器系列,其具有集成型高精度基准。这些器件保证具备单调特性,并具有内置的轨至轨输出缓冲器。这些 SoftSpan™ DAC 提供了 5 种输出范围,最高达 ±10V。每个通道的范围可单独设置,或者,也可以针对某种固定范围内的运作对器件进行硬件配置。
集成型 2.5V 基准单独缓冲至每个通道;一个外部基准可用于提供附加的范围选项。另外,LTC2664 还具备通过一个专用引脚或软件切换命令实现的 A/B 切换能力。
可兼容 SPI / Microwire 的三线式串行接口可依靠低至 1.71V 的逻辑电平在高达 50MHz 的时钟速率下操作。
