product details
Ad8313 is a complete multi-stage demodulated logarithmic amplifier, which can accurately convert the RF signal at the input end to the equivalent DB scale value of 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 simple, requiring only a single power supply of 2.7 V to 5.5 V and adding appropriate input and power coupling. When powered by 3 V power supply, the power consumption of 13.7 MA (for TA = 25 ° C) is only 41 MW. It has power saving characteristics. The input is pulled up to start low current (20 μ a) sleep mode, and the threshold is half of the power supply voltage.
Ad8313 is manufactured by ADI's advanced 25 GHz Silicon Bipolar IC process, and provides 8-pin MSOP package. The operating temperature range is from? 6? 140 ° C to + 85 ° C.
