  • Description

    The LA1845N/1845NM is a single-chip tuner IC designed for use in mini systems. It provides electronic tuning functions using SD/IF-count technique, allowing for additional parts reduction. This IC incorporates a pilot canceler and an adjustment-free MUX VCO circuit, providing a compact and efficient solution for electronic tuning in mini systems.

    Specifications and features


    • AM: RF amplifier, mixer, oscillator, IF amplifier, detector, AGC, SD, oscillator buffer, IF buffer, stereo IF output, AGC time constant switch
    • FM IF: IF amplifier, quadrature detector, S-meter, SD (signal detection), S-curve detection, IF buffer output
    • MPX: PLL stereo decoder, stereo display, forced monaural, VCO stop, audio muting, adjacent channel interference rejection function, pilot canceler


    • Integrated MPX VCO (ceramic resonators are no longer required.)
    • Built-in adjacent channel interference rejection function (114 kHz, 190 kHz)
    • Supports both SD and IF-count techniques
    • Both FM SD sensitivity and bandwidth can be set
    • Pilot canceler built-in

    Application Scenarios

    The LA1845N/1845NM tuner IC is suitable for use in mini systems where electronic tuning functions are required. It can be used in various audio and entertainment devices.


    The advantages of the LA1845N/1845NM model include its compact design, integrated MPX VCO, and built-in adjacent channel interference rejection function. Its support for both SD and IF-count techniques allows for flexible tuning options. However, the IC may have limitations in terms of specific signal detection sensitivity and bandwidth settings, which should be considered based on the application requirements.
