Small footprint, 2 mm × 3 mm LFCSP
Supply operation: 3.0 V to 5.5 V at 22 mA
Fabricated using high speed SiGe process Figure 1. GENERAL DESCRIPTION
The AD8317 is a demodulating logarithmic amplifier, capable
of accurately converting an RF input signal to a corresponding
decibel-scaled output. It employs the progressive compression
technique over a cascaded amplifier chain, each stage of which
is equipped with a detector cell. The device can be used in either …
