S1A0427B01
INTRODUCTION
The S1A0427B01 is a monolithic integrated circuit designed for portable AM/FM radios or AM/FM clock radios. 16DlP300A
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: VCC = 3V 12V (Approximately ) (Depending on the internal regulator tolerance) Recommended operating suply voltage: VCC = 4.5V 9V Vcc RL 8 16 45 4.5V O O O 6.0V O O O 7.5V O O O 9.0V X O O Line Operated X X O
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/8 ).
