DESCRIPTION
The CD7613 is a monolithic integrated
circuit designed for the portable AM/FM radio or AM/FM clock radios.
FEATURE
z z 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.
