AD8313 is a wide bandwidth 0.1 GHz - 2.5 GHz, 70 dB dynamic range linear detector / controller, with high accuracy, high response, large output, wide power supply voltage range and other features
The AD8313 is a multistage demodulating logarithmic amplifier designed for RF measurement and power‑amplifier control from 0.1 GHz to 2.5 GHz. It converts a differential RF input to a dc voltage that represents the signal level in decibels, offering a high dynamic range and low‑power operation.
The document includes functional block diagrams, detailed electrical specifications, absolute‑maximum ratings, pin descriptions, ordering information, and typical performance graphs. It also describes both logarithmic (RSSI) and controller modes, along with recommended supply ranges and ESD handling guidelines.
