Analog Devices Inc. AD9625 12 位，2.0GSPS ADC
Analog Devices AD9625 12 位、2.0GSPS 模数转换器（ADC）具有同类中最佳的噪声和动态范围，从而实现更好的接收器灵敏性，并能在出现噪声、混杂信号、阻塞源和干扰源的情况下识别出更好的信号。该 ADI A/D 转换器被设计用于对第二奈奎斯特区域的宽带宽模拟信号进行采样。AD9625 集宽输入带宽、高采样率和优异的线性度等优点于一身，非常适合于超宽带雷达、数字存储示波器用宽带前端、数据采集平台等应用。模拟输入、时钟和 SYSREF± 信号是差分输入。基于 JESD204B 的高速串行输出可在 1、2、4、6 或 8 通道排列中进行配置。该 ADI 器件额定工作于从 −40°C到 +85°C 的工业温度范围。
These ADI A/D converters are designed for sampling wide bandwidth analog signals up through the second Nyquist zone. AD9625 features a combination of wide input bandwidth, high sampling rate, and excellent linearity that make it ideal for use in ultra-wide band RADAR, wideband front-ends for digital storage oscilloscopes, and data acquisition platforms. The analog input, clock, and SYSREF± signals are differential inputs. The JESD204B-based high-speed serialized outputs are configurable in a variety of one, two, four, six-lane, or eight-lane arrangements. These ADI devices are specified over the industrial temperature range of −40°C to +85°C.
