功能描述
LTC2637 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/°C 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。LTC2637-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。LTC2637-H 具有一个 4.096V 全标度输出，并采用 4.5V 至 5.5V 的单电源工作。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。LTC2637 工作于标准模式 (100kHz 时钟频率) 和快速模式 (400kHz 时钟频率)。LTC2637 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。
