The LOG200 is a precision, high-speed, current-to-voltage logarithmic amplifier with integrated adaptive photodiode bias. The device is designed for current measurements across a wide dynamic range of 10pA to 10mA (180dB). It features a high-speed response spanning several decades of input current, allowing for a unique combination of fast transient response with high accuracy and logarithmic conformity.

This document provides guidelines, examples, and bench measurements, interfacing the LOG200 with photosensors for optical current sensing applications.
