The AD8310 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. It 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. A single supply voltage of 2.7 V to 5.5 V at 8 mA is needed, corresponding to a power consumption of only 24 mW at 3 V. A fast-acting CMOS-compatible enable pin is provided.
