Product Details

This evaluation board provides full access to all analog and digital inputs/outputs on the ADAU1777. The ADAU1777 core is controlled by Analog Devices, Inc., SigmaStudio™ software, which interfaces to the board via a USB connection. The This evaluation board provides full access to all analog and digital inputs/outputs on the ADAU1777. The ADAU1777 core is controlled by Analog Devices, Inc., SigmaStudio™ software, which interfaces to the board via a USB connection. The EVALADAU1777Z can be powered by a single AAA battery, by the USB bus, or by a single 3.8 V to 5.5 V supply; any of these supplies are regulated to the voltages required on the board. The printed circuit board (PCB) is a 4-layer design, with a single ground plane and a single power plane on the inner layers. The board contains connectors for external microphones and speakers. The master clock can be provided externally or by the on-board 12.288 MHz passive crystal.
