Product Summary

The AD8310ARMZ is a complete, demodulating logarithmic amplifier (log amp) with a very fast voltage mode output, capable of driving up to 25 mA into a grounded load in under 15 ns. The AD8310ARMZ uses the progressive compression (successive detection) technique to provide a dynamic range of up to 95 dB to ±3 dB law conformance or 90 dB to a ±1 dB error bound up to 100 MHz. It is extremely stable and easy to use, requiring no significant external components. The applications of the AD8310ARMZ include 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 analyzers, Signal-level determination down to 20 Hz, True-decibel ac mode for multimeters.
