It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. Amplifiers based on BA does not require an output coupling transformer and datashret be operated from a single supply. The operating voltage range is from 5 to 15V DC. This makes the IC suitable for low power car audio applications.

bs5406 Other applications of BA are portable audio players, stereo component systems, television etc. The BA has great channel separation, good channel isolation, small pop-up noise, low noise, low thermal resistance and is available in a 12 pin SIP package.


5×2 watt BA stereo amplifier . Operates from 9V DC. Low distortion.

Capacitor C3 is a power supply filter capacitor. C11 and C12 are input DC decoupling capacitors for the left and right channels. Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier. Potentiometers R5 and R6 serves as the volume control for the left and right channels.

CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers. C9 and C10 are noise filtering capacitors.

C1 and C5 are bootstrap capacitors for the left and right channels. Hi, what kind of a heatsink does BA need? I tried to search for SIP package heatsinks, but nothing good came up.
