LA3430 Description

Short technical summary and product information.

The LA3430 is a Monolithic Linear IC from ROHM Semiconductor, specifically designed as an MPX IC for FM car stereo systems. It features a non-adjusting VCO, which eliminates the need for free-running frequency adjustments and offers stability against ambient temperature changes. The IC includes a pilot cancel function (Level follow-up type), stereo noise control (SNC function), and high cut control (HCC function) to enhance audio quality.

Additional functions include stereo-monaural automatic selection, prioritizing pilot input, and a VCO oscillation stop function. A forced monaural function is also available for reception modes. The LA3430 operates within a wide voltage range of 6.5V to 13V, with a recommended supply voltage of 10V. It exhibits low distortion, typically 0.07%, and good power supply ripple rejection of 35dB.

Packaged in a 16-pin SIP (SIP16Z) with a 3mm pin-to-pin space, the LA3430 is designed for easy integration into printed circuit boards. Its through-hole mounting type and compact package contribute to efficient board layout. The operating temperature range is -20°C to 45°C, with a storage temperature range of -40°C to 125°C.
