数据采集ADC/DAC – 专业 IC 14-BIT SYNC TO DIGITAL CNVTR
Product Details
The SDC1740 is a hybrid 14-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 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.
