Analog Devices AD8315 RF Detector/Controller Product Handbook
The AD8315 is a complete low‑cost subsystem for precise control of RF power amplifiers in the 0.1 GHz‑2.5 GHz range, offering a typical 50 dB dynamic range. It is intended for cellular handsets and other battery‑operated wireless devices, with temperature‑stable linear‑in‑dB response.
The device supplies a voltage output (VAPC) that can directly drive handset power‑amplifier gain pins, and a setpoint input (VSET) with a 0.25 V‑1.4 V range. Pin functions, typical performance curves, and ordering options are detailed in the handbook.
