Analog Devices AD8369 Datasheet
The AD8369 is a high‑performance digitally controlled variable gain amplifier (VGA) that provides a 45 dB gain range in 3 dB steps from low frequencies to a 3‑dB bandwidth of 600 MHz. It features a 4‑bit parallel or 3‑wire serial interface, differential 200 Ω input and output impedance, and operates from a single 3.0‑5.5 V supply drawing 37 mA at 5 V.
Typical applications include cellular/PCS base stations, IF sampling receivers, fixed wireless access, wireline modems, and instrumentation. The device is supplied in a 16‑lead TSSOP package (RU‑16) for the industrial temperature range –40 °C to +85 °C, and an evaluation board is available.
