to the EVAL-ADAU1850EBZ via a USB connection. The
development kit (SDK)
is also provided by Analog Devices for code
development.
The EVAL-ADAU1850EBZ can be powered by the USB bus or by
a single 3.8 V to 5 V supply. These supply options are regulated
to the voltages required on the EVAL-ADAU1850EBZ. The printed
circuit board (PCB) is a 4-layer design, with a ground plane and
a power plane on the inner layers. The EVAL-ADAU1850EBZ
contains connectors for external microphones and speakers. The
master clock can be generated through the internal RC oscillator in
the absence of an external clock source. It also can be provided
externally or by the on-board 24.576 MHz oscillator.
