DEM-DAI1770/1771 Evaluation Board
The DEM-DAI1770/1771 is an evaluation board for the PCM1770/1771, a 24-bit, 50-kHz, two-channel audio DAC with digital audio receiver, mode control switch, analog mixing input, stereo headphone output, and more.
Although the PCM1770/1771 requires a 2.5-V or 3.3-V supply, the DEM-DAI1770 operates from a 5-V analog power supply with S/PDIF input signal and has an outboard 2.5-V or 3.3-V voltage regulator. In order to control the PCM1770/1771, demonstration software (only for PCM1770) is provided. This software controls the device via a PC-compatabile parallel port.
