PPSS88553636
High-Fidelity Full-Digital Amplifier for USB Speakers
USB Streaming Audio Processor
with 4Wx2 Speaker Amplifier
Introduction_____________________ Features________________________
PS8536 is a highly integrated system-on-chip solution for
USB speaker applications. It combines all essential active
parts including USB interface, a high-performance stereo
PWM modulator, a sophisticated sample rate converter, a
stereo speaker amplifier and state-of-art digital signal pro-
cessing.
Built-in USB interface supports both 5V power supply and
adaptive isochronous transfer for playback. On-chip full-
digital stereo speaker amplifier is rated at -watt per channel
with 96% efficiency under the external power source, 6.0V
PS8536 fully supports sound processing including five-band
equalizer, dynamic range control (DRC), mute, volume, and
auto gain limiter. The equalizer setting may be selected from
a large set of preset equalizer pool optimized for the most
popular speakers in the market. With PS8536, you could
easily apply the button controls for bass, treble, dynamic
range control, volume and mute controls.
Through the on-chip I2S interface, the PS8536 may also re-
ceive additional digital sources. I2C control bus and GPIO
allows full compatibility and easy configuration.

fier.
No additional active components for USB speakers re-
quired.
