AD8307 Datasheet (Analog Devices) - Logarithmic Amplifier

AD8307, Logarithmic Amplifier

The AD8307 is the first logarithmic amplifier made available in an 8-lead SOIC_N package.

It is a complete 500 MHz monolithic demodulating logarithmic amplifier based on the progressive compression (successive detection) technique, providing a dynamic range of 92 dB to ±3 dB law conformance and 88 d
