AD8313ARM-REEL

0.1千兆赫， 2.5千兆赫， 70分贝对数检测器/控制器 0.1 GHz-2.5 GHz, 70 dB Logarithmic Detector/Controller

Product Details

The AD8313 is a complete multistage demodulating logarithmic amplifier that can accurately convert an RF signal at its input to an equivalent decibel-scaled value at its dc output. The AD8313 maintains a high degree of log conformance for signal frequencies from 0.1 GHz to 2.5 GHz. Application is straightforward, requiring only a single supply of 2.7 V to 5.5 V and the addition of a suitable input and supply decoupling. Operating on a 3 V supply, its 13.7 mA consumption for TA = 25°C is only 41 mW. A power-down feature is provided; the input is taken high to initiate a low current 20 µA sleep mode, with a threshold at half the supply voltage

The AD8313 is fabricated on Analog Devices, Inc., advanced 25 GHz silicon bipolar IC process and is available in an 8-lead MSOP package. The operating temperature range is −40°C to +85°C.
