    Figure 1. GENERAL DESCRIPTION
    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 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 CMOScompatible enable pin is provided. Each of the six cascaded amplifier/limiter cells has a smallsignal gain of 14.3 dB, with a -3 dB bandwidth of 900 MHz. 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 supplyand 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 grea ...
