Analog Devices Inc. AD9683 14位模数转换器

Analog Devices AD9683 14位模数转换器的最高采样速率可达250MSPS。ADI AD9683 旨在为低成本、小尺寸、宽带宽、多功能通信应用提供解决方案。ADC内核采用多级、差分廉线结构，并集成了输出纠错逻辑。ADC内核还具有宽带宽输入，支持用户可选的各种输入范围。集成基准电压源可简化设计。需要时，灵活的掉电选项可以明显降低功耗。

The ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. The core also features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. Flexible power-down options allow significant power savings, when desired.
