SA2104S

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. SDIP-24-300-1.778 FEATURES * Operating supply voltage range: VCC=1.8~10V (Tamb=25°C) * For NEW FCC * FM/AM and MPX integrated in a single-chip. * Build in FM/AM IF count buffer. FM: 1.3375MHz (1/8 dividing) AM: 450kHz * Build in mute circuit for IF count output according to field strength. * Build in FM MPX VCO circuit * Build in FM/AM OSC buffer output for DTS applications. * Build in AM low cut circuit * Build in stereo indicator. * Low supply current. (VCC=3V, Tamb=25°C) ICCq (FM)=11.0mA (Typ.) ICCq (AM)=7.5mA (Typ.)
