AD8310ARMZ

AD8310 is a complete, DC to 440MHz demodulating logarithmic amplifier (log amp) with a very fast voltage mode output, capable of driving up to 25mA into a grounded load in under 15ns. It uses the progressive compression (successive detection) technique. Typical application includes conversion of signal level to decibel form, transmitter antenna power measurement, receiver signal strength indication(RSSI), low cost radar and sonar signal processing, network and spectrum analysers, signal-level determination down to 20hz true-decibel and ac mode for multimeters.
