... The MAX4206’s uncommitted op amp can be used for a variety of functions, including filtering noise, adding offset, and adding additional gain. A 0.5V reference is also included to generate an optional precision current reference using an external resistor, which adjusts the log intercept of the MAX4206 ...

... BE2 Figure 3. Ideal Transfer Function with Varying K Referred-to-Input and Referred-to-Output Errors The log nature of the MAX4206 insures that any addi- tive error at LOGV1 corresponds to multiplicative error at the input, regardless of input level. Total error (TE) is defined as the deviation of the output ...

... The MAX4206 incorporates leakage current compensation and high-current correction circuits to compensate for these errors. The MAX4206’s frequency response is a function of the input current magnitude and the selected compensation (100µA/100nA) network at LOGIIN and REFIIN. The compensation net- ...
