特性
- 8 通道 / 16 通道单端或 4 通道 / 8 通道差分输入 (LTC2414 / LTC2418)
- 低电源电流 (200μA，在自动睡眠模式中为 4μA)
- 差分输入和具 GND 至 VCC 共模范围的差分基准
- 2ppm INL，无漏失码
- 2.5ppm 全标度误差和 0.5ppm 偏移

LTC®2414 / LTC2418 是 8 通道 / 16 通道 (4 通道 / 8 差分通道) 微功率、24 位 ΔΣ 模数转换器。它们采用 2.7V 至 5.5V 工作电源，并具有一个集成型振荡器、2ppm INL 和 0.2ppm RMS 噪声。这些器件采用增量-累加技术并提供了适合多路复用应用的单周期稳定时间。可通过单个引脚对 LTC2414 / LTC2418 进行配置以在 50Hz 或 60Hz ±2% 频率下实现优于 110dB 的输入差模抑制，也可针对一个用户定义的抑制频率由一个外部振荡器来驱动 LTC2414 / LTC2418。内部振荡器无需外部频率设定组件。
LTC2414 / LTC2418 接受介于 0.1V 至 VCC 之间的任何外部差分基准电压，适合于灵活的比例式和远端采样测量应用。可对它们进行配置以接受4 / 8 差分通道或 8 / 16 单端通道。全标度双极输入范围为 –0.5VREF 至 0.5VREF。基准共模电压 VREFCM 和输入共模电压 VINCM 可独立地设定在 GND 至 VCC 范围之内。DC 共模输入抑制性能优于 140dB。
LTC2414 / LTC2418 通过一个与 SPI 和 MICROWIRE 协议相兼容的灵活四线式数字接口进行通信。

特性和优点
- Analog Devices has worked closely with Intel PSG to develop verified power solutions that optimize cost, size and efficiency in high performance applications.
- The validated power solutions include uModules power products that address time and space constraints while delivering high efficiency, reliability, and low noise.
- The actual power tree represents the best solution at time of design.
- A recommended power tree has also been included to present the ideal solution at time of Stratix 10 GX PCIe development kit release. An updated alternate version of the power tree represents the latest solutions available from Analog Devices. For many applications, an intermediate rail is not ideal, so recommendations an alternate power tree that allow for direct power conversion from 12V input is provided below.
