AN7289NFBQ
FM-FE+AM IC for car radio
s Overview
The AN7289NFBQ is an IC having FM-FE+AM
functions for car radio. A tuner block of car radio can be
constructed by using this IC and the AN7293NSC/NFBQ.
s Features
• A less number of electrolytic capacitors is required (3
capacitors reduction compared with our conventional
IC)
• AM: Effective sensitivity is improved by 2 dB through
ATC
• AM: Strong-input characteristic is improved by 2-loop-
AGC function
• The AN7289NSC of DIL package type is also available
s Applications
• Car radios
