AD677: 16位串行100 kSPS采样ADC
AD677是一款多用途16位串行输出模数转换器 ， 利用开关电容/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。AD677电路分为两个单芯片：数字控制芯片采用ADI公司的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。AD677的信纳比、总谐波失真和交调失真等交流（或“动态”）参数，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。AD677采用+5 V和±12 V电源供电 ， 使用10 V基准电压源时 ， 转换期间的功耗通常为450 mW（使用5 V基准电压源时为360 mW） 。 数字电源(VDD)与模拟电源(VCC、VEE) 分离 ， 以减少数字串扰 。 提供模拟参考地 ， 可远程检测信号源的地电位 。 如果信号必须传播一定距离才能到达A/D转换器 ， 此器件会非常有用 。 此外还提供独立的模拟地和数字地。AD677采用16引脚窄体塑封DIP封装、16引脚窄体侧面钎焊陶瓷封装或28引脚SOIC封装。AD676为并行输出版本，采用28引脚陶瓷或塑封DIP封装。所有型号的工作温度范围为0℃至+70℃商用温度范围或-40°C至+85°C工业温度范围。
The AD677 is a multipurpose 16-bit serial 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 AD677 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 AD677 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 AD677 operates from +5 V and ±12 V supplies and typically consumes 450 mW using a 10 V reference (360 mW with 5 V reference) during conversion. The digital supply (VDD) is separated from the analog supplies (VCC, VEE) for reduced digital crosstalk. An analog ground sense is provided to remotely sense the ground potential of the signal source. This can be useful if the signal has to be carried some distance to the A/D converter. Separate analog and digital grounds are also provided.The AD677 is available in a 16-pin narrow plastic DIP, 16-pin narrow side-brazed ceramic package, or 28-lead SOIC. A parallel output version, the AD676, is available in a 28-pin ceramic or plastic DIP. All models operate over a commercial temperature range of 0°C to +70°C or an industrial range of -40°C to +85°C.
