LTC®2641/LTC2642 是 16、14 和 12 位无缓冲电压输出DAC 系列。这些 DAC 采用 2.7V 至 5.5V 单工作电源,并在整个温度范围内保证单调。LTC2641A-16/LTC2642A-16 在整个温度范围内提供了16 位性能 ((±1LSB INL 和 ±1LSB DNL)。无缓冲 DAC 输出产生了 120μA 的低电源电流和 ±1LSB 的低偏移误差。
LTC2641 和 LTC2642 均具有一个 2V 至 VDD 的基准输入范围。VOUT 摆幅为 0V 至 VREF。对于双极操作,LTC2642 包括供一个外部精准运算放大器 (例如:LT1678) 之用的匹配调节电阻器,并在 RFB 上产生一个 ±VREF 输出摆幅。
LTC2641/LTC2642 采用一个简单的 SPI/MICROWIRE 兼容型三线式串行接口,能够以高达 50MHz 的时钟速率来运行,并可直接与光耦合器相连,以适应那些需要隔离的应用。最初加电时,上电复位电路将 LTC2641 的 DAC 输出清至零标度,并把 LTC2642 的 DAC 输出清至中间标度。CLR 引脚上的一个逻辑低电平将把 DAC 异步清至零标度 (LTC2641) 或中间标度 (LTC2642)。这些 DAC 均具有商业和工业规格范围。
