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
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
