• Notes

• AM One Chip Radio

   The TA7641BP is designed for the portable AM Radio applications
   and provides all of the functions from the converter to power
   amplifier. It is designed to make the quiescent current very
   small (1.6mA Typ. at V_CC=3V) by use of the idle current
   control circuit.

  So it is capable to design the portable radio set
  with merit that the battery life is very long.
  
   - Low Quiescent Current: I_CCQ=1.6mA(Typ.) at V_CC=3V
   - Operating Supply Voltage Range: V_CC=2~5V
   - High Power Efficiency
   - Power Output: P_O=100mW(Typ.) at THD=10% 
  Das Taschenradio ist Made in India.
