AN7289NSC
FM-FE+AM IC for car radio
s Overview
The AN7289NSC is an IC having FM-FE+AM
functions for car radio. A tuner block of car radio
can be constructed by combination of this IC and
the AN7293NSC / NFBQ.
s Features
• A less number of electrolytic capacitors is required
(3 capacitors reduction compared with our con-
ventional IC)
• AM: Practical sensitivity is improved by 2 dB by
ATC
• AM: Strong input characteristics is improved by
2-loop AGC function
s Applications
• Car radios
