LTC2636-8 具 10ppm/ºC 基准的 8 通道 8 位 SPI Vout DAC

LTC®2636 是一个 8 通道 12 位、10 位和 8 位电压输出 DAC 系列,具有一个集成、高准确度、低漂移 10ppm/ºC 基准,采用 14 引脚 DFN 和 16 引脚 MSOP 封装。它内置一个轨至轨输出缓冲器,并保证具有单调特性。LTC2636-L 具有一个 2.5V 全标度输出,并采用 2.7V 至 5.5V 的单工作电源。LTC2636-H 具有一个 4.096V 全标度输出,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。

这些 DAC 通过一个 SPI / MICROWIRE 兼容型三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。采用 MSOP 封装的器件提供了硬件清除 (CLR) 和异步 DAC 更新 (LDAC) 引脚。LTC2636 内置了一个上电复位电路。提供了在上电之后于内部基准模式中复位至零标度或复位至中间标度、或于外部基准模式中复位至中间标度的选项。
