AD8307ARZ

AD8307 is a low cost, logarithmic amplifier. It is extremely stable and easy to use, requiring no significant external components. A single-supply voltage of 2.7V to 5.5V at 7.5mA is needed. A fast acting CMOS compatible control pin can disable the device to a standby current of 150μA. It is widely used in application such as conversion of signal level to decibel form, transmitter antenna power measurement, receiver signal strength indication (RSSI), low cost radar and sonar signal processing, network and spectrum analysers (to 120 dB), signal level determination down to 20Hz, true decibel ac mode for multimeters etc.
