Description AD8313 is a complete multi stage demodulation logarithmic amplifier which can accurately convert the RF signal at the input into the equivalent dB scale value at the DC output AD8313 can maintain high logarithmic consistency in the signal frequency range of 0 1 GHz to 2 5 GHz The application is very simple just need a single power supply from 2 7 V to 5 5 V and add the appropriate input and power supply coupling When it is powered by a 3 V power supply the 13 7 mA power consumption for TA 25°C is only 41 mW It has power saving features the input is pulled high to start a low current 20 μA sleep mode and the threshold is half of the power supply voltage AD8313 is manufactured using ADI s advanced 25 GHz silicon bipolar IC process and is available in an 8 pin MSOP package The operating temperature range is −40°C to 85°C Specification 1 Operating frequency 0 1 GHz to 3 5 GHz2 High dynamic range 70 dB to ±3 0 dB3 High precision ±1 0 dB 65 dB range 1 9 GHz 4 Fast reaction 40 ns full scale typical value 5 Controller mode with error output6 The adjustment ratio does not change with the power supply voltage and temperature7 Wide power supply voltage range 2 7 V to 5 5 V8 Low power consumption 40 mW 3 V 9 Power saving features 60 mW 3 V 10 Size 50 50 9mm11 Product weight 20 gramsPackage included 1 x Logarithmic Amplifier
