Audio, Power Management,
IDTP95020-EVAL
Description
The IDTP95020 evaluation board serves to demonstrate
the features and performance of the IDTP95020 Audio,
Power Management and Control integrated circuit. The
intuitive top-level layout and control switches simplify the
user experience to emphasize the impressive level of
integration and abundance of useful features that this
device offers.
The device can be powered and controlled by a single
mini-USB input. If more input power is required, a DC
input from wall adapter can be connected.
The external EEPROM memory chip is pre-programmed
with a basic start-up script that is automatically loaded
when power is applied. The device can be reprogrammed
to suit the needs of your specific application using the
IDTP92020 software tool.
The core layout is a 6-layer reference that can be copied
and integrated into a larger system design.
