LTC2635-12 - 具 10ppm/ºC 基准的 4 通道 12 位 I2C Vout DAC

LTC®2635 是一个 4 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 16 引脚 QFN 或 10 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。LTC2635-L 具有一个 2.5V 全标度输出，并采用 2.7V 至 5.5V 单工作电源。LTC2635-H 具有一个 4.096V 全标度输出，并采用 4.5V 至 5.5V 单工作电源。每个 DAC 也可以采用一个外部基准来运作，这将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，LTC2635 工作于标准模式 (时钟速率为 100kHz) 和快速模式 (时钟速率为 400kHz)。LTC2635 内置了一个上电复位电路。可提供的选项包括：复位至零标度、在内部基准模式中复位至中间标度、于外部基准模式中复位至中间标度、或在上电之后的一种高阻抗状态中与所有的 DAC 输出一起复位。
