• Streaming support for MP3 and WAV
• EarSpeaker Spatial Processing
• Bass and treble controls
• Operates with a single clock 12..13 MHz

• Internal PLL clock multiplier
• Low-power operation
• High-quality on-chip stereo DAC with no
phase error between channels
• Stereo earphone driver capable of driv-
stereo DAC, followed by an earphone ampli-
fier and a common voltage buffer.
VS1033 receives its input bitstream through
a serial input bus, which it listens to as a
system slave. The input stream is decoded
and passed through a digital volume control
to an 18-bit oversampling, multi-bit, sigma-
delta DAC. The decoding is controlled via a
ing a 30 Ω load
serial control bus. In addition to the basic de-
• Quiet power-on and power-off
• I2S interface for external DAC
• Separate operating voltages for analog,
digital and I/O
coding, it is possible to add application spe-
cific features, like DSP effects, to the user
RAM memory.
• 5.5 KiB On-chip RAM for user code /
data
• Serial control and data interfaces
• Can be used as a slave co-processor
• SPI flash boot for special applications
• UART for debugging purposes
• New functions may be added with soft-
EarSpeaker spatial processing provides more
natural sound in headphone listening condi-
tions. It widens the stereo image and posi-
tions the sound sources outside the listener’s
head.
