AD641 General Description

The AD641 is a 250 MHz, demodulating logarithmic amplifier with an accuracy of ± 2.0 dB and 44 dB dynamic range. The AD641 uses a successive detection architecture to provide an output current that is logarithmically proportional to its input voltage. The output current can be converted to a voltage.
