Description

General part information

BH3544F Series

BH3544F is digital-source headphone amplifier. BH3544F has a fixed gain of 6 dB, so external gain setting is not needed. Mute function can make it easy to perform countermeasures to prevent pop noise when the power supply turns ON or OFF. Moreover, built-in thermal shutdown circuits prevent IC destruction due to short circuits.
