The AD8307ANZ is a 500MHz Monolithic Demodulating Logarithmic Amplifier based on the progressive compression (successive detection) technique, providing a dynamic range of 92dB to ±3dB law conformance and 88dB to a tight ±1dB error bound at all frequencies up to 100MHz. It is extremely stable and easy to use requiring no significant external components. A single-supply voltage of 2.7 to 5.5V at 7.5mA is needed. A fast acting CMOS-compatible control pin can disable the AD8307 to a standby current of 150μA. The amplifier is ideal for use in conversion of signal level to decibel form, transmitter antenna power measurement and receiver signal strength indication (RSSI) as well as low cost radar and sonar signal processing.
