The AD8367 is a 500 MHz linear-in-dB variable gain amplifier with AGC detector. It features a broad-range analog variable gain, linear-in-dB gain control, and resistance to interference.
The AD8367 is a 500 MHz linear‑in‑dB variable gain amplifier with integrated AGC detector, offering a gain range of –2.5 dB to +42.5 dB and single‑supply operation from 2.7 V to 5.5 V. It features a 9‑stage resistive attenuator, a fixed‑gain feedback amplifier, and on‑chip square‑law detection for precise output level control.
The datasheet includes detailed specifications, absolute maximum ratings, pin configuration, typical performance graphs, and guidance on AGC operation, power management, and application circuits such as cellular base stations and broadband access.
