The AD640 is a plete monolithic logarithmic amplifier.

A single AD640 provides up to 50 dB of dynamic range for frequencies from dc to 120 MHz.

Two AD640s in cascade can provide up to 95 dB of dynamic range at

Complete, Fully Calibrated Monolithic System Five Stages, Each Having 10 dB Gain, 350 MHz BW Direct Coupled Fully Differential Signal Path Logarithmic Slope, Intercept and AC Response are Stable Over Full Military Temperature Range Dual Polarity Current Outputs Scaled 1 mA/Decade Voltage Slope Options (1 V/Decade, 100 mV/dB, etc. ) Low Power Operation (Typically 220 mW at ؎5 V) Low Cost Plastic Packages Also Available.
