ICs for FM/AM Tuner
n Overview
The AN7017S and the AN7017SB are the ICs incorpo-
rating FM/TV front-end most suitable for headphone
stereo.
Sealed in a 16-pin flat package, the chip operates sta-
bly at TV band (170MHz ~ 222MHz) FM band (76MHz ~
108MHz).
RF amplifiers and oscillations are provided in FM/TV
band individually, and are designed most suitably. So
both characteristics of FM/TV band are satisfied.
n Features
• Low current consumption
• Band switching circuit built-in
• A single chip integrating FM/TV band
• IF amp. built-in
