The AD8337 is a low noise, single-ended, linear-in-dB, general-purpose variable gain amplifier (VGA) usable in a variety of applications, including signal tuning, video enhancement, image enhancement, and signal enhancement. It features low noise, wide bandwidth, high gain range, and low power consumption.
The AD8337 is a general‑purpose, low‑cost, DC‑coupled variable gain amplifier (VGA) covering frequencies from DC to 100 MHz with a –3 dB bandwidth of 280 MHz. It offers low voltage and current noise, a gain range of 0 dB to 24 dB, and linear‑in‑dB gain scaling of 19.7 dB/V. The device can be powered from single‑ or dual‑supply configurations (+2.5 V, +5 V, or dual supplies) and consumes only 78 mW at +2.5 V.
The document includes functional block diagrams, pin configuration tables, absolute maximum ratings, typical performance curves, and detailed specifications such as bandwidth, noise, distortion, and power consumption. It also provides application guidance for gain‑trim, PET scanners, ultrasound, radar receivers, and video systems, along with thermal and ESD handling recommendations.
