RDC1740: 14位混合型自整角机/旋变数字转换器

RDC1740 功能框图 RDC1740是一款混合型14位连续跟踪旋变数字转换器，其核心部分的转换过程由一个采用ADI公司专有BiMOS II工艺制造的单芯片IC来执行；该工艺将CMOS逻辑和双极性高精度线性电路两种技术的优势结合在同一芯片上。该器件采用内部隔离微变压器，来完全隔离信号和参考输入。14位数字字以三态数字格式提供，分为两个字节。高字节8位和低字节6或4位分别采用单独的ENABLE输入，这样不仅能简化多个器件在单条数据总线上的复用，而且使得INHIBIT输入的使用不会中断跟踪环路的操作。这款转换器采用32引脚金属焊接密封封装。

The RDC740 is a hybrid 14-bit continuous tracking resolver to digital converter. In the core of this hybrid, the conversion process is performed by a monolithic IC manufactured in Analog Devices proprietary BiMOS II process that combines the advantages of CMOS logic and bipolar high accuracy linear circuits on the same chip. Internal isolating micro-transformers are used to provide true isolation of the signal and reference inputs. The 14-bit digital word is in a three-state digital form available in two bytes. Using separate ENABLE inputs for the most significant 8 bits and the least significant 6 or 4 bits not only simplifies multiplexing off more than one device onto a single data bus, but also enables the INHIBIT input to be used without interrupting the operation of tracking loop. The converters are hermetically sealed in a 32-pin welded metal package.
