Logarithmic amplifiers

Logarithmically scaled outputs for a wide, dynamic range of voltage or current inputs

Our logarithmic amplifiers are designed for measuring low-level and wide dynamic range currents common in optical modules, lasers, and medical equipment. These devices offer low log conformity and wide dynamic range capability and are offered in tiny 4-mm x 4-mm lead-less packages for space constrained applications.
