我厂生产的对数功能块有80L_1及80L_2两种型号,分别用于正向直流输入信号及负向直流输入信号。采用进口元器件和先进线路,内有温度补偿和体电阻补偿,所以其模块精度较高。改变管脚接法,可作直流电压对数放大器、直流电流对数放大器、反对数放大器。模块与线性组件组合,还可进行乘法、除法及倒数等运算。上述功能块使用方便,现已小批量生产。一、技术指标
The logarithmic function block that our factory produces has 80L_1 and 80L_2 two kinds of models, respectively for the positive direct current input signal and the negative direct current input signal. Imported components and advanced lines, there are temperature compensation and body resistance compensation, so its higher module accuracy. Change the pin connection, can be used for DC voltage logarithmic amplifier, DC current logarithmic amplifier, anti-logarithmic amplifier. Combination of modules and linear components, but also for multiplication, division and countdown and other operations. The above function block easy to use, is now small batch production. First, the technical indicators
