Overview
The LA1225MC is a Low-voltage operation (1.8V or higher) FM IF detector IC for the electronic tuning system.
Features
Low-voltage operation (1.8V or higher)
Supports electronic tuning systems (provides built-in SD output and IF count output functions)
FM detector circuit accepts an even wider input frequency range. (Supports the use of an external phase capacitor.)
Miniature package: SOIC10
