LTC2633A-12 具 10ppm/ºC 基准的双通道 12 / 10 / 8 位 I2C Vout DAC

LTC®2633 是一个双通道 12 位、10 位和 8 位电压输出 DAC 系列,具有一个集成、高准确度、低漂移基准,采用 8 引脚 TSOT-23 封装。它内置轨至轨输出缓冲器,并保证具有单调特性。LTC2633-L 具有一个 2.5V 的全标度输出,并采用 2.7V 至 5.5V 的单工作电源。LTC2633-H 具有一个 4.096V 的全标度输出,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 通过一个二线式 I2C 兼容型串行接口进行通信,LTC2633 工作于标准模式 (时钟速率为 100kHz) 和快速模式 (时钟速率为 400kHz)。LTC2633 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、或于一种高阻抗状态中和所有的 DAC 输出一起复位的选项。
