The AD8367 is a high performance 45 dB variable gain amplifier with linear-in-dB gain control for use from low frequencies to 500 MHz.
The AD8367 is a high‑performance variable‑gain amplifier that provides a gain range of –2.5 dB to +42.5 dB (45 dB total) with linear‑in‑dB scaling of 20 mV/dB. It features a 9‑stage resistive input ladder, a fixed‑gain feedback stage, and an on‑chip square‑law detector for AGC applications. The device operates from low frequencies up to 500 MHz and can be powered from a single supply of 2.7 V to 5.5 V.
Typical applications include cellular base stations, broadband access, power‑amplifier control loops, and high‑speed data I/O. The AD8367 is supplied in a 14‑lead TSSOP package rated for –40 °C to +85 °C operation and includes pins for gain control, mode selection, enable, and detector output.
