Headphone Amplifiers  
Digital Input  
Class-D Headphone Amplifier  
BU7839GVW  
No.10102EAT03  
Description  
Most suitable for long duration reproduction of digital audio because digital audio data is taken as its input and low power  
consumption is realized.BU7839GVW has Stereo Audio DAC and HP amp functions for digital audio playback.  
Pop sound in ramp-up period is reduced due to built-in start-up sound reduction circuit or transistor for mute.  
Also, Built-in digital volume which can control L-ch & R-ch separately.  
Features  
1) With Stereo Audio DAC and HP amp functions  
2) Most suitable for long duration reproduction of digital audio because digital audio data is  
taken as its input and low power consumption is realized  
3) Pop sound in ramp-up period is reduced due to built-in start-up sound reduction circuit or transistor for mute  
4) Built-in digital volume which can control L-ch & R-ch separately  
Immediate switching and zero cross switching for reduction of clicking sound at the time of gain change  
Gain change methods of soft switching can be selected with registers  
5) Sampling frequency compatible with 8kHz-48kHz  
6) Compatible with master slave with built-in PLL  
7) Built-in soft mute function  
8) Compatible with full front and full back formats  
9) Compatible with 16, 18 & 24bit formats  
10) Compatible with fs=32kHz,44.1kHz,48kHz with de-emphasis function  
11) 2wire CPU I/F (2 addresses selectable 33h, 36h)  
Functions  
Stereo Audio DAC + HPamp  
2wire CPU I/F  
Serial audio I//F
