Sometimes we do not want a linear response from an op amp circuit. For example, what if we want the output voltage to represent the natural logarithm of the input voltage?
The AD8307 is the first logarithmic amplifier made available in an 8-lead (SOIC_N) package. It is a complete 500 MHz monolithic demodulating logarithmic amplifier based on the ...
A logarithmic video amplifier or LVA is typically part of radar and electronic countermeasures microwave systems and sonar navigation systems, used to convert a very large dynamic ...
