µPC1857A  
SOUND CONTROL IC WITH SURROUND AND I2C BUS  
DESCRIPTION  
The µPC1857A is a sound control IC with I2C bus.  
It has functions to control volume, balance, and tone, and a phase shift matrix surround function.  
The surround function achieves wide sound expansion using only two front speakers. Three modes can be  
selected: movie mode that increases the presence of sound with stereo sound input, music mode emphasizing vocal  
music, and simulated mode that gives expansion and left and right sound depth with monaural sound input.  
The µPC1857A can perform all control (mode switching, volume control and so on) using I2C.  
FEATURES  
Volume control function  
Balance control function  
: Attenuation adjustable from 0 to 80 dB in 64 steps  
: The difference in attenuation adjustable from 0 to 80 dB in 64 steps  
Tone (bass, treble) control function : Adjustable in 32 steps from +10 to 10 dB  
Surround function (gain adjustable) : Three modes (movie, music, and simulated)  
Mute function  
Mixing function  
Output selection function (for two mono channels input)  
All parameters can be controlled via I2C bus.  
APPLICATIONS  
TV, PC monitor
