Headphone amplifier for CD-ROMs
BH3541F / BH3544F
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.
