Monolithic Linear IC
Home Stereo Single-Chip Tuner IC with Electronic Tuning Support
The LA1835 is an AM, FM IF and MPX single-chip tuner IC that supports electronic tuning. It was developed specifically for use in home stereo products and is optimal for products with auto-seek systems, since it combines SD and IF counting in its auto-seek implementation. Furthermore, since the FM detector and MPX VCO circuits are adjustment free, adoption of the LA1835 can reduce the number of adjustment steps in the production line.
