AD676: 16位并行100 kSPS采样ADC

AD676 功能框图 AD676是一款多用途16位并行输出模数转换器，采用开关电容/电荷再分配架构，转换速率达100 kSPS（10 µs总转换时间）。通过片内自动校准功能对内部非线性进行数字校正，从而优化整体性能。AD676电路分为两个单芯片：数字控制芯片采用ADI公司DSP CMOS工艺制造，模拟ADC芯片采用BiMOS II工艺制造。两个芯片集成于单封装内。AD676的信纳比、总谐波失真和交调失真等交流（或“动态”）参数性能，对于信号处理应用极为重要。此外，直流参数对测量应用也至关重要。AD676采用+5 V和±12 V电源供电，转换期间的典型功耗为360 mW。数字电源(VDD ) 与模拟电源(VCC 、 VEE ) 分离，以减少数字串扰。针对模拟输入提供了模拟参考地。此外还提供独立的模拟地和数字地。AD676采用28引脚塑封DIP或28引脚侧面钎焊陶瓷封装。AD677为串行输出版本，采用16引脚300 mil宽陶瓷或塑封封装。

The AD676 is a multipurpose 16-bit parallel output analog-to-digital converter which utilizes a switched-capacitor/charge redistribution architecture to achieve a 100 kSPS conversion rate (10 µs total conversion time). Overall performance is optimized by digitally correcting internal nonlinearities through on-chip autocalibration.The AD676 circuitry is segmented onto two monolithic chips- a digital control chip fabricated on Analog Devices DSP CMOS process and an analog ADC chip fabricated on our BiMOS II process. Both chips are contained in a single package.The AD676 is specified for ac (or "dynamic") parameters such as S/(N+D) Ratio, THD and IMD which are important in signal processing applications. In addition, dc parameters are specified which are important in measurement applications.The AD676 operates from +5 V and ±12 V supplies and typically consumes 360 mW during conversion. The digital supply (VDD ) is separated from the analog supplies (VCC , VEE ) for reduced digital crosstalk. An analog ground sense is provided for the analog input. Separate analog and digital grounds are also provided.The AD676 is available in a 28-pin plastic DIP or 28-pin side-brazed ceramic package. A serial-output version, the AD677, is available in a 16-pin 300 mil wide ceramic or plastic package.
