The LA3433 is an MPX IC designed for FM car‑stereo applications. It integrates a non‑adjusting VCO, pilot‑cancellation, stereo‑noise‑control (SNC) and high‑cut control (HCC) functions, and can operate in both stereo and forced‑monaural modes.
The document provides maximum ratings, operating conditions, detailed characteristic curves, and example application circuits. Electrical specifications such as supply voltage range, quiescent current, channel separation and harmonic distortion are listed for designers.
