LTC1864 采用 MSOP 封装的微功率、16 位、250ksps 单通道和双通道ADC
LTC®1864/LTC1865 是采用 MSOP 和 SO-8 封装的 16 位 A/D 转换器，采用单 5V工作电源。在 250ksps 采样速率条件下，电源电流仅为 850μA。在较低的速度下，电源电流将减小，原因是 LTC1864/LTC1865 在转换操作之间自动断电。这些 16 位开关电容器逐次逼近型 ADC 包括采样及保持电路。LTC1864 具有一个差分模拟输入和一个可调基准引脚。LTC1865 提供了一个可利用软件来选择的双通道 MUX 和一个可调基准引脚 (在 MSOP 封装版本上)。
三线式串行 I/O、小外形 MSOP 或 SO-8 封装、以及极高的采样速率与功率之比使得这些 ADC 非常适合于紧凑、低功率、高速系统。
这些 ADC 可在比例式应用中使用，或与外部基准一起使用。高阻抗模拟输入以及可在缩减的电压范围内 (低至 1V 全标度) 运作的能力使得它们在许多应用中可与信号源直接相连，从而免除了增设外部增益级的需要。
