Analog Devices AD8314 Logarithmic Amplifier Datasheet
The AD8314 is a complete RF detector/controller subsystem designed for cellular handsets and other wireless devices. It measures and controls RF signals from 0.1 GHz to 2.5 GHz, offering a 45 dB dynamic range and temperature‑stable linear‑in‑dB response.
Key features include a low supply current (12 mW at 2.7 V), power‑down mode with 20 µA draw, two voltage outputs (V_UP for measurement and V_DN for control), and an 8‑lead micro‑SOIC package. The device is specified for operation from –30 °C to +85 °C.
