Description
The CD7613 is a monolithic integrated circuit designed for the portable AM/FM radio or AM/FM clock radios.
Features
Portable AM/FM 1-chip radio Wide op erating su pp ly voltage range: Vcc=3V~12V (Approxi mately) (Depending on the internal regulator tolerance) z Recommen ded operating supply voltage : Vcc=4.5V~9V On using AC line as an internal shunt regulator mode , it is transformer (approximately possible to use low cost application without a 42mA). z z IF AMP gain is determined by DC Vo ltage appeared at IC Pin16 Power output: Po=0.28W (Min.) at THD=10% (Vcc=5.5V/8 )
