LTC2654-12 - 具10ppm/ºC 最大值基准的四通道、12 位、轨至轨 DAC
LTC®2654 是一个 4 通道 16 位 / 12 位轨至轨 DAC 系列，具有集成 10 ppm/ºC最大值基准。这些DAC 具有内置的高性能、轨至轨输出缓冲器，并保证具有单调特性。LTC2654-L 具有一个 2.5V 的全标度输出和集成基准，并采用 2.7V 至 5.5V 的单工作电源。LTC2654-H 具有一个 4.096V 的全标度输出和集成基准，并采用 4.5V 至 5.5V 的单工作电源。每个 DAC 也可以采用一个外部基准来运作，该外部基准负责将 DAC 全标度输出设定为外部基准电压的两倍。 这些 DAC 通过一个 SPI/MICROWIRETM 兼容型四线式串行接口进行通信，该接口在高达 50MHz 的时钟频率条件下工作。LTC2654 包括一个受控于 PORSEL 引脚的上电复位电路。如果 PORSEL 引脚连接至 GND，则 DAC 被复位至零标度。如果 PORSEL 引脚连接至 VCC，则 DAC 将被复位至中间标度。
