SDC1742: 12位自整角机数字转换器

SDC1742 功能框图 SDC1742是一款混合式12位连续跟踪自整角机数字转换器。在这款混合器件的内核中，转换过程由基于ADI专有BiMOS II工艺制成的一个单芯片IC完成，在同一芯片中有机地结合了CMOS逻辑和双极性高精度线性电路的优势。通过内部隔离微变压器实现信号与基准电压输入之间的真正隔离。12位数字字采用三态数字形式，由2个字节构成。通过为最高有效8位和最低有效6位或4位分别配置ENABLE输入，不但简化了将一个器件以多路复用方式连接至单个数据总线的过程，同时为INHIBIT输入提供了支持，无需中断跟踪环路的操作。该转换器密封于32引脚焊接金属封装之中。

The SDC1742 is a hybrid 12-bit continuous tracking synchro 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 12-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.
