Ordering number : ENN 7931 www.DataSheet4U.com LA1845NV Monolithic Linear IC Single-Chip Home Stereo IC The LA1845NV 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.
Functions AM : RF amplifier, mixer, oscillator, IF amplifier, detector, AGC, SD, oscillator buffer, IF buffer
LA1845NV 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 i
