AD8307ARZ
Overview
The AD8307ARZ is a complete multi-stage logarithmic amplifier capable of converting an input signal at frequencies up to 500 MHz into a proportional decibel-scaled DC voltage. It features a dynamic range of approximately 92 dB, allowing for precise measurement of signal strength across a wide power spectrum. Operating from a 2.7V to 5.5V supply, it consumes only 7.5 mA of typical current, making it suitable for battery-powered RF instrumentation.
Why Choose This Part
The AD8307ARZ provides exceptional linearity and temperature stability, maintaining accuracy across its -40C to +85C operating range. Its progressive compression technology eliminates the need for external log-processing circuitry, significantly reducing PCB footprint in space-constrained designs.
Applications
Key Specifications
Getting Started
To evaluate this part, use the AD8307-EVALZ evaluation board which provides SMA connectors for RF input and test points for the DC output. Ensure the input is AC-coupled if the source has a DC offset, and place bypass capacitors as close to the VPOS pin as possible to minimize noise in high-frequency applications.
