The BH3541F and BH3544F are digital-source dual headphone amplifiers. The BH3541F has a fixed gain of 0dB and the BH3544F has a fixed gain of 6dB so that external gain setting is unnecessary. Both the BH3541F and BH3544F have internal mute functions so that prevention of the popping sound when power is turned on and off is greatly simplified.
Also, these ICs are equipped with thermal shutdown circuits to prevent damage from short circuits.

FEATUREs
1) Internal mute function to prevent popping sounds when the power is turned on and off.
2) Built-in thermal shutdown circuit (150°C) to prevent damage to the IC if a short circuit occurs.
3) Compact SOP8 pin package.

APPLICATIONs
    Devices that use the headphone output from CD-ROMs, CDs, MDs, personal computers, notebook computers, camcorders, etc.
