MAX4206 Datasheet | Maxim Integrated

EVALUATION KIT AVAILABLE Precision Transimpedance Logarithmic Amplifier with Over 5 Decades of Dynamic Range General Description The MAX4206 logarithmic amplifier putes the log ratio of an input current relative to a reference current (externally or internally generated) and provides a corresponding voltage output with a default 0.25V/decade scale factor. The device operates from a single +2.7V to +11V supply or from dual ±2.7V to ±5.5V supplies and is capable of measuring five decades of input current across a 10nA to 1mA range. The MAX4206’s unmitted op amp can be used for a variety of functions, including filtering noise, adding offset, and adding additional gain. A 0.5V...
