INTRODUCTION
The S1A0427B01 is a monolithic integrated circuit designed for
portable AM/FM radios or AM/FM clock radios.
16−DlP−300A
FUNCTIONS
• AM RF & MIX
• AM AGC
• AM/FM DET
• Regulator
• AM Local OSC
• AM/FM IF AMP
• Audio Power AMP
• FM AFC Control
FEATURE
• Portable AM/FM 1-chip radio
• Wide operating supply voltage range: V_CC = 3V − 12V (Approximately )
(Depending on the internal regulator tolerance)
• Recommended operating suply voltage:
V_CC = 4.5V − 9V

• When using the AC line as an internal shunt regulator mode, it is possible to use a low cost application without
a transformer (approximately 42mA)
• IF AMP gain is determined by the DC voltage appearing at IC Pin 16.
• Power output: PC = 0.28W (Min.) at THD = 10% (Vcc = 5.5V/8Ω).
