Analog Devices ADL5519 Dual Log Detector/Controller Datasheet
The ADL5519 from Analog Devices is a dual‑channel logarithmic detector and controller designed for RF power measurement and control applications. It integrates two AD8317 log amplifiers and provides independent log‑scaled outputs, difference outputs, and a temperature‑compensated sensor.
The device operates from 3.3 V to 5.5 V, consumes about 60 mA, and is packaged in a 5 mm × 5 mm, 32‑lead LFCSP. It supports a wide frequency range (1 MHz‑10 GHz), offers a 62 dB dynamic range, and includes interfaces for set‑point, voltage reference, power‑down, and temperature compensation.
