The EVAL-AD1940AZ provides a full range of analog and digital inputs and outputs to and from the AD1940. The SigmaDSP can connect to analog I/O signals through the AD1939 codec and AD1974 ADC. Digital I/O connections are available in both S/PDIF and 3-wire serial data formats. The DSP is controlled by Analog Devices’ SigmaStudioTM software, which interfaces to the evaluation boards with a USB cabke via the EVAL-ADUSB2EBZ add-on board, also known as the USBi. Power is distributed by a single DC supply, which is regulated tothe necessary voltages on the board. The PCB is an 7” × 5” 4-layer design with split analog and digital power and ground planes on the two inner layers.
The AD1940 evaluation board should be used for AD1941 evaluation. There is no AD1941 evaluation board.
