Audio ICs AM radio / FM IF stereo system IC BA1450S

The BA1450S is a tuner system IC for electronic tuning for AM radios, FM IF, and MPX. It has been developed for Hi-Fi component applications. The MPX VCO circuit requires no adjustment, which will enable a reduction in the number of production line processes. In particular, the laser lock technique used in the VCO means that no external adjustment is required. Applications Synthesized tuner for Hi-Fi components. Features 1) Built-in AM monaural radio, FM IF amplifier /detector, 6) Built-in forced monaural operation function for MPX and FM stereo demodulator. (VCO stops, and LED goes off). 2) DTS (both SD and IF count) compatible. 7) Low cutoff of audio is possible to improve AM fidelity. 3) Built-in reference voltage power supply provides 8) MPX VCO stops in AM mode. good shortwave band frequency stability. 9) Audio muting is possible when an IF request is made. 4) Good FM stability. 5) The FM MPX VCO uses laser locking making adjust- ment and external components unnecessary.
