【摘要】 文中提出一种性能优良的单片集成数字增益设定器LFl3006/7,它与集成运算放大器组成可编程增益放大器PGA电路,也可组成具有二进制或者十进制等不同增益档次的程序可测控的仪表放大器。微机系统通过接口电路对它实施智能式的增益切换,优化了仪器测量的动态范围和精度,这对人们无法手动干预的环境监测或海洋遥测过程有特殊的意义。更多还原

【Abstract】 This paper presents an excellent monolithic integrated digital gain set LF 13006 (or LF13007). It can be combined with an integrated OP-Amplifier as a PGA. Also, it may be constructed as a programmable instrumentation amplifier with binary or decimal gain. Through the interface circuit, the micro computer system gives effect to the intelligent gain interchange for the optimum dynamic testing range and precision. It is specially significant to interfere no-manually an environmental or oceanic process which is being monitored or remotely tested.更多还原
