Ordering number : EN7930A www.DataSheet4U.com Monolithic Linear IC LA1844 LA1844M Overview For Home Stereo Single-chip Tuner IC The LA1844, LA1844M is designed for use in mini systems and is a single-chip tuner IC that provides electronic tuning functions using SD/IF-count technique. It incorporates a pilot canceler and an adjustment-free MUX VCO circuit, thus allows additional parts to be reduced. Features • Integrated MPX VCO (ceramic resonators are no longer required.) • Built-in adjacent channel interference rejection function (114kHz, 190kHz) • Supports both SD and IF-count techniques • Both FM SD sensitivity and bandwidth can be set • Pilot canceler built in.
