ADI ADAQ8088双路模拟系统级封装(SIP)开发方案

ADI公司的ADAQ8088是双路模拟系统级封装(SIP),集成了三个信号处理和蔼调理区块,支持多种解调器应用和数据采集应用.器件集成了所有的有源和无源元件,形成I/Q解调器输出和ADC输入之间的完整信号链.器件还在基带数据采集系统的换能器输出和ADC输入之间的形成完整信号链.对这些适当功能不需要外接元件.每一路包括预放大器,接着是36MHz 3dB的8极点低通滤波器和一个差分ADC驱动器,驱动12位到14位流水线ADC,速率高达150MSPS.采用6 mm × 12 mm CSP_BGA封装, ADAQ8088在高密度多路系统中最大限度降低了空间需求.工作电压2.7V到3.3V,工作温度−40C 到 +85C.3V电源时的功耗为213mW,最大差分增益为30dB,可调整低至14dB,增益误差为±0.2 dB,增益漂移为0.01dB/度C.主要用在IF宽带解调器,医疗图像,相阵列系统,雷达,自适应天线通信接收器,无线电链接,无线局部回路,RF仪表,卫星调制解调器,基带数据采集系统,多路数字化仪表以及超声波无损伤测试.本文介绍了ADAQ8088主要特性,功能框图和应用电路,评估板EVAL-ADAQ8088EBZ主要特性和框图以及AD9681-125EBZ和HSC-ADC-EVALEZ连接图,电路图,材料清单和PCB设计图.

 

 The ADAQ8088 is a dual-channel analog system in package (SIP) that integrates three common signal processing and conditioning blocks to support a variety of demodulator applications and data acquisition applications. The device integrates all active and passive components to form a complete signal chain between the output of an I/Q demodulator and the input to an analog-to-digital converter (ADC). The device also forms the complete signal chain between a transducer output and the input to an ADC in baseband data acquisition systems. No external components are required for proper functi
