SA2104/SA2104S
3V AM/FM+MPX TUNER IC(FOR DIGITAL TUNING SYSTEM)
DESCRIPTION
The SA2104/SA2104S are single-chip tuner ICs that incorporate
FM/AM and MPX circuits, which are designed for portable radios and 3V
headphone radios.
The SA2104/SA2104S are suitable for digital tuning system
applications. FM local oscillation voltage is set up low relativity, for NEW
FCC.
