Product Summary

The AD8307ARZ is the first logarithmic amplifier made available in an 8-lead (SOIC-8) 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 dB to a tight ±1 dB error bound at all frequencies up to 100 MHz.

Parametrics

AD8307AR absolute maximum ratings: (1)Supply: 7.5 V; (2)Input Voltage: VSUPPLY; (3)Storage Temperature Range, N, R: -65 to +125℃; (4)Ambient Temperature Range: -40 to +85℃; (5)Lead Temperature Range: 300℃.

Features

AD8307AR features: (1)Complete multistage logarithmic amplifier; (2)92 dB dynamic range: –75 dBm to +17 dBm to –90 dBm using matching network; (3)Single supply of 2.7 V minimum at 7.5 mA typ; (4)DC to 500 MHz operation, ±1 dB linearity; (5)Slope of 25 mV/dB, intercept of -84 dBm; (6)Highly stable scaling over temperature; (7)Fully differential dc-coupled signal path; (8)100 ns power-up time, 150 μA sleep current.
