Product Summary

The AD8310ARMZ is a complete, dc-440 MHz 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. The applications of the AD8310ARMZ include: (1)Conversion of Signal Level to Decibel Form; (2)Transmitter Antenna Power Measurement; (3)Receiver Signal Strength Indication (RSSI); (4)Low-Cost Radar and Sonar Signal-Processing; (5)Network and Spectrum Analyzers; (6)Signal-Level Determination Down to 20 Hz; (7)True-Decibel AC Mode for Multimeters.
