The AD8314 is a complete RF detector/controller for the measurement and control of RF signals in the frequency range of 0.1 GHz to 2.5 GHz. It provides a wide dynamic range and better accuracy, with excellent temperature stability.
The AD8314 is a low‑cost, logarithmic RF detector/controller covering 100 MHz to 2.5 GHz with a typical dynamic range of 45 dB. It offers two voltage outputs (V_UP for measurement and V_DN for control) and includes internal AC‑coupling, low power consumption, and a power‑down mode.
The device is supplied in an 8‑lead micro‑SOIC package, operates from 2.7 V to 5.5 V, and is rated for –30 °C to +85 °C. Detailed pin descriptions, absolute maximum ratings, and typical performance graphs are provided, along with evaluation‑board configuration options and mechanical dimensions.
