This is another stereo / dual power amplifier circuit with power IC KA series. This amplifier delivers dual power output (stereo) at 1.2W for each channel. General

2 x 1.2W Dual Power Amplifier with KA2214

The KA2214 is a monolithic integrated dual audio power amplifier in a 14-pin plastic dual in line package. It is designed portable audio sets.

Power IC KA2214 Features:

  • Wide operating supply voltage range: Vcc=3V~13V
  • Output power:
    Po = 1.2W at 9V/8?/THD = 10%
    Po = 1.6W at 9V/4?/THD = 10%
    Po = 2W at 12V/8?/THD = 10%
  • Good ripple rejection ratio: 50dB (Typ)
  • Low quiescent circuit current: 10mA (Vcc=9V)
  • Minimum number of external parts required
