LTC2655 - 具10ppm/ºC 最大值基准的四通道、I2C、16 位 / 12 位、轨至轨 DAC
LTC®2655 是一个 4 通道、I2C、16 位 / 12 位、轨至轨 DAC 系列，具有集成 10ppm/ºC 最大值基准。这些DAC 具有内置的高性能、轨至轨输出缓冲器，并保证具有单调特性。LTC2655-L 具有一个 2.5V 的全标度输出和集成基准，并采用 2.7V 至 5.5V 的单工作电源。LTC2655-H 具有一个 4.096V 的全标度输出和集成基准，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的两倍。 这些器件采用二线式 I2C 兼容型串行接口。LTC2655 工作于标准模式 (最大时钟频率为 100kHz) 和快速模式 (最大时钟频率为 400kHz)。LTC2655 包括一个受控于 PORSEL 引脚的上电复位电路。如果 PORSEL 引脚连接至 GND，则 DAC 在上电时被复位至零标度。如 果 PORSEL 引脚连接至 VCC，则 DAC 在上电时将被复位至中间标度。
