This is a 5watt stereo power amplifier used IC BA5406. IC 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. Ideally the power supply should be able to deliver over 2.5 Amps. 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.

Skema rangkaian 2 x 5 watt Amplifier IC BA5406 Description
The BA5406 is a monolithic dual OTL power amplifier containing two sets of high-power AF power amplifiers. The device delivers 5 watts x 2 into 30 loads with a 12V supply, or 2.8 watts x 2 into 30 loads with a 9V supply. The BA5406 features minimal power-on pop noise and immunity to supply voltage drop. With its minimal RF radiation, the device is ideally suited for use in stereo radio cassette recorders.

Features IC BA5406
Minimal power-on pop noise.
Immunity to supply voltage drop (operates down to Vcc=4.5V typ.).
Excellent channel balance.
Low distortion (THD=0.3% at PO=O.5W).
12.pin SIP package for mounting ease and saved space on a PC board.
Ripple filter input (pin 6) can also be used as a muting control input.
Symmetrical pin configuration facilitates art work.
Low thermal resistance of the package makes heat-sink design easy.
Built-in high-frequency phase compensation capacitor.
Minimal RF radiation allows for free system layout.
