MAX4206
EVALUATION KIT AVAILABLE
Precision Transimpedance Logarithmic Amplifier with Over
5 Decades of Dynamic Range
General Description
The MAX4206 logarithmic amplifier computes 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 uncommitted op amp can be used for a variety of functions, including filtering noise, adding offset, and adding additional gain.
