BH3541F H3544F,BH3547F,BH3548F
Description
BH3541F, BH3544F, BH3547F, BH3548F is headphone amplifiers suitable for portable products.
BH3541F has a fixed gain of 0 dB and BH3544F, BH3547F, BH3548F has a fixed gain of 6 dB.
External resistors for gain setting are not needed. Package of BH3541F, BH3544F, BH3547F, BH3548F is pin-to-pin
compatible (SOP8), enable to replace each other easily.
BH3541F, 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.
BH3541F, BH3544F, BH3547F can drive 16/32 load, BH3548F can drive 8/16/32 . So, BH3548F is suitable for 8
receiver.
Features
1) Built-in mute function for preventing pop noise when power supply turns on/off
2) Built-in thermal shutdown function
3) BH3541F, BH3544F, BH3547F, BH3548F are pin-to-pin compatible
4) SOP8 small package
