Packaged in a ceramic double wide DIP, the 4127 is the first hybrid logarithmic amplifier that accepts signals of either polarity from current or voltage sources. A special purpose monolithic chip, developed specifically for logarithmic conversions,functions accurately for up to six decades of input current and four decades of input voltage. In addition, a current inverter and a precise internal reference allow pin programming of the 4127 as a logarithmic, log ratio, or antilog amplifier. To further increase its versatility and reduce your system cost, the 4127 has an uncommitted operational amplifier in its package that can be used as a buffer, inverter, filter, or gain element. The 4127 is available with initial accuracies (logconformity) of 0.5% and 1.0%, and operates over an ambient temperature range of -10oC to +70oC. With its versatility and high performance, the 4127 has many applications in signal compression, trans-ducer linearization, and photo tube buffering. Manufacturers of medical equipment, analytical instruments, and process control instrumentation will find the 4127 a low cost solution to many signal processing problems.
