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 ...

An Logarithmic amplifier is good example of why we need to be careful to call these types of devices analog, not linear devices – because these are certainly not linear. Log amps can be a ...
