AD8313 - Logarithmic Detector/Controller

Datasheet Summary

Description

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.

Features

  • Wide bandwidth: 0.1 GHz to 2.5 GHz min.
  • High dynamic range: 70 dB to ±3.0 dB.
  • High accuracy: ±1.0 dB over 65 dB range (@ 1.9 GHz).
  • Fast response: 40 ns full-scale typical.
  • Controller mode with error output.
  • Scaling stable over supply and temperature.
  • Wide supply range: 2.7 V to 5.5 V.
  • Low power: 40 mW at 3 V.
  • Power-down feature: 60 mW at 3 V.
  • Complete and easy to use.
