AD8313
Overview
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.
- 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
