PRODUCT OVERVIEW
OVERVIEW
The S5A1901H02, Audio Effect Processor, reproduces vivid sound of
certain places and dynamic sound of movies. The S5A1901H02 has
over 15 sound effect modes including two kinds of Karaoke mode. In
addition to the sound modes, the S5A1901H02 provides mic-echo,
vocal canceller, loudness function, graphic equalizer, spectrum ana-
lyzer interface, tone control and volume/balance control so that it can
satisfy various sound requirements of audio systems including TV,
stereo audio systems, etc. Furthermore, the S5A1901H02 has built-in
16 bit stereo
-
ADC and DAC for easy application. The
S5A1901H02 also includes two digital source interface blocks and a
host interface block supporting normal microcontroller and I
2
C bus
interfaces.
