4127 is the first hybrid logarithmic amplifier with double width DIP ceramic package, it can accept either polarity signal from the current source or voltage source. 4127 is the ASIC chip for logarithmic transformation with accurate 6 decimal input current and 4 decimal input voltage. In addition, a current inverter and an internal precision reference make pin programmable to complete the functions of logarithmic, logarithmic ratio and antilog amplifier. In order to further increase its versatility and reduce the cost of the user's system, the internal 4127 encapsulates an operational amplifier which can be used as a buffer, filter or gain elements. The initial accuracy of 4127 is 0.5% and 1.0%, and it can work in ambient temperature range of -10 ~ +70 ℃. The 4127 versatility and high performance have many uses, such as signal compression, sensor linearization, light electrical buffer, as well as in the manufacturing of medical devices, analytical instrumentation and process control instruments.
