The AD8310 is a complete, dc to 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 total of nine detector cells are used to provide a dynamic range that extends from ?91 dBV (where 0 dBV is defined as the amplitude of a 1 V rms sine wave), an amplitude of about ?40 ?V, up to +4 dBV (or ?2.2 V). The demodulated output is accurately scaled, with a log slope of 24 mV/dB and an intercept of ?108 dBV. The scaling parameters are supply- and temperature-independent.The fully differential input offers a moderately high impedance (1 k? in parallel with about 1 pF). A simple network can match the input to 50 ? and provide a power sensitivity of ?78 dBm to +17 dBm. The logarithmic linearity is typically within ?0.4 dB up to 100 MHz over the central portion of the range, but it is somewhat greater at 440 MHz.
