ADI ADAQ7980 16位模数转换器(ADC)子系统开发方案
ADI公司的ADAQ7980/ADAQ7988是16位模数转换器(ADC)子系统,集成了四个常见信号处理和调理模块,采用支持各种应用的封装(SiP)设计.器件内置一个高精度低功耗16位SARADC,一个低功耗高带宽高输入阻抗ADC驱动器,一个稳定的低功耗基准电压缓冲器和一个高效的电源管理模块,工作温度范围为−55°C至+125°C,主要用在自动测试设备(ATE),电池供电仪器仪表,通信,数据采集,过程控制和医疗仪器.本文介绍了ADAQ7980/ADAQ7988主要特性,功能框图,应用电路,以及评估板EVAL-ADAQ7980SDZ主要特性,框图,电路图,材料清单和PCB设计图.
The ADAQ7980/ADAQ7988 are 16-bit analog-to-digital converter (ADC) subsystems that integrate four common signal processing and conditioning blocks into a system in package (SiP) design that supports a variety of applications. These devices contain the most critical passive components, eliminating many of the design challenges associated with traditional signal chains that use successive approximation register (SAR) ADCs. These passive components are crucial to achieving the specified device performance.
