The AD8367 is a high-performance 45 dB variable gain amplifier with linear gain control for use from low frequencies up to several hundred megahertz. The range, flatness, and accuracy of the gain response are achieved using Analog Devices’ X-AMP® architecture, the most recent in a series of powerful proprietary integrated circuits.
The AD8367 is a high‑performance 45 dB variable‑gain amplifier that provides linear‑in‑dB gain control from –2.5 dB to +42.5 dB. It features a resistive 200 Ω input ladder, an on‑chip square‑law detector for AGC, and a single‑supply range of 2.7 V to 5.5 V. The device is offered in a 14‑lead TSSOP package suitable for –40 °C to +85 °C operation.
Typical applications include cellular base stations, broadband access, power‑amplifier control loops, and high‑speed data I/O. An evaluation board and a set of recommended external components are provided to simplify integration and testing.
