This R-2R ladder DAC is developing around Intel / Altera *EPM240T100C5N* CPLD.\n\nDAC which described in this repo can directly connect with the I2S interface of Raspberry Pi boards. The recommended supply voltage for this DAC is 5V to 8V.\n\nThe *MCP602* opamp of this module is capable to drive headphone directly. An external AF power amplifier must pair with this module to obtain a higher output power.\n\nThis repository contains all the files and binaries to build DAC, which including *Intel Quartus* Project files, Raspberry Pi Device Tree Overlays, etc.\n\nThis is certified open-source hardware project.
