THAT2252 Overview
The THAT 2252 integrated-circuit rms-level detector is designed to convert an ac input current into a dc output voltage. The output is proportional to the log of the true rms value of the input signal. The parts are housed in a space-efficient plastic 8-pin single-in-line (SIP) package, and require minimal support circuitry.
