This is a 24-bit stereo DAC, which is specifically built for Raspberry Pi boards. This R-2R ladder DAC is developing around Intel / Altera EPM240T100C5N CPLD.
DAC 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.
The 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.
This repository contains all the files and binaries to build DAC, which including Intel Quartus Project files, Raspberry Pi Device Tree Overlays, etc.
