The BA5406 contains two sets of AF power amplifiers. It delivers 5W x 2 into 3 ohm loads with a 12V supply. It has minimal power-on pop noise and has immunity to supply voltage drop. It also has minimal RF radiation.
Recommended supply voltage: 5-15V max. Typical 12V. Ideally the power supply should be able to deliver over 2.5Amps. This means that a typical ‘cheap’ plugin power supply (wall wart) will not be good enough. The power supply leads should be as short as possible. Quiescent current 20-70mA, typically 40mA.
