LTC2631 - 具 10ppm/ºC 基准的单通道 12 / 10 / 8 位 I2C VOUT DAC

LTC®2631 是一个采用 8 引脚 TSOT-23 封装、具有一个集成、高准确度、低漂移基准的 12 位、10 位和 8 位电压输出 DAC 系列。它内置一个轨至轨输出缓冲器，并保证具有单调特性。 LTC2631-L 具有一个 2.5V 的全标度输出，并采用 2.7V 至 5.5V 单工作电源。LTC2631-H 具有一个 4.096V 的全标度输出，并采用 4.5V 至 5.5V 单工作电源。在 REF 引脚上提供了一个 10ppm/ºC 基准输出。 每个 DAC 都能够工作于外部基准模式，在该模式中，一个提供至 REF 引脚的电压负责设定全标度输出。 LTC2631 DAC 采用一个二线式、I2C 兼容型串行接口。LTC2631 可工作于标准模式 (100kHz 时钟频率) 和快速模式 (400kHz 时钟频率)。

LTC2631 内置一个上电复位电路。提供了在上电之后复位至零标度或复位至中间标度的选项。
