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 ...

FEMTO’s logarithmic wideband voltage amplifier HLVA-100 has a wide dynamic range of 0dB to 80dB, with DC coupled input and a fast rise/fall time of 5ns for a 40dB step. The noise for the device is ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...
