The MAX3524 is a single‑ended input, differential‑output low‑noise amplifier (LNA) designed for cable television receivers and cable modem applications. It provides 15 dB of voltage gain, a low noise figure of about 4.2 dB, and high linearity (IIP2 ≈ 42 dBm, IIP3 ≈ 14 dBm) across a 44 MHz‑to‑880 MHz band.
The device operates from a single 4.75 V‑5.25 V supply, draws up to 95 mA, and includes an on‑chip operational amplifier for controlling an external PIN attenuator. Detailed pin descriptions, package outlines, and application notes are provided for PCB layout and biasing considerations.
