AD9226 12位、65 MSPS ADC

AD9226是一款单芯片、12位、65 MSPS模数转换器(ADC),采用单电源供电,内置一个片内高性能采样保持放大器和基准电压源。它采用多级差分流水线架构,数据速率达65 MSPS,在整个工作温度范围内保证无失码。

该ADC采用高速、低成本的CMOS工艺及新颖的架构,分辨率和速度可达到现有双极性方案的水平,而功耗成本却低得多。

AD9226的输入能够与成像、超声和通信系统实现轻松接口。利用真差分输入结构,用户可以选择包括单端应用在内的各种输入范围和偏移。动态性能极为出色。

采样保持放大器既适用于在连续通道中切换满量程电平的多路复用系统,也适合采用最高Nyquist速率及更高的频率对单通道输入进行采样。

AD9226采用先进的CMOS工艺制造,提供28引脚超薄紧缩小型封装(28 TSSOP)和48引脚超薄四方扁平封装(48-LQFP),额定温度范围为-40°C至+85°C工业温度范围。
