●Description
BH3544F, BH3547F, BH3548F are headphone amplifiers suitable for portable products. BH3544F, BH3547F, BH3548F has
a fixed gain of 6 dB. External resistors for gain setting are not needed. Package of BH3544F, BH3547F, BH3548F is
pin-to-pin compatible (SOP8), enable to replace each other easily.
BH3544F, BH3547F, BH3548F also has mute functions that make it easy to prevent pop noise when power supply turns
on/off. Moreover, thermal shutdown function is built-in.BH3544F, BH3547F can drive 16/32
load, BH3548F can drive
8/16/32
. So, BH3548F is suitable for 8 receiver.
●Features
