Analog Devices Inc. AD9625 12 位模数转换器评估板

Analog Devices AD9625 评估板是一款用于 AD9625 的 12 位单片式采样模数转换器（ADC）的开发工具。ADI AD9625 可工作于高达 2.5GSPS 的转换速率下，被设计用于对宽幅带宽模拟信号进行采样。AD9625 可用于高至第二奈奎斯特区域。AD9625-2.0EBZ用于AD9625-2.0 (2.0GSPS)，AD9625-2.5EBZ用于AD9625-2.5 (2.5GSPS)。该模数转换器集宽输入带宽、高采样率和优异的线性度等优点于一身，非常适合于频谱分析仪、数据采集系统以及各式军工电子应用，比如雷达和干扰/抗干扰测量。

AD9625 can be used up to the second Nyquist zone. AD9625-2.0EBZ is for AD9625-2.0 (2.0GSPS) and AD9625-2.5EBZ is for AD9625-2.5 (2.5GSPS). The ADCs' combination of wide input bandwidth, high sampling rate, and excellent linearity is ideal for spectrum analyzers, data acquisition systems, and a wide assortment of military elections applications, such as RADAR and jamming/anti-jamming measures.
