About the Dac attack PCB

Dac attack is an open source PCB design by saybur, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 71.8 × 26 mm, with 62 components from 25 distinct parts.

Other key parts include the CS8416-xZZ, PCM5100, SD6210A, XC6206P332MR and TCM809. By type, the board carries 28 capacitors, 18 resistors, 7 connectors, 6 ICs, 2 test points and 1 inductor.

It belongs with the audio and retro computing designs in this gallery.

From the project

S/PDIF to line-level audio board for use with retro computer device emulators, such as ZuluSCSI and friends.

A small S/PDIF to line-level audio adapter design. The intended use case is with some versions of ZuluSCSI, though the design should work with any S/PDIF compatible output source generating a TTL-compatible signal.

Used with a compatible board, and the appropriate firmware, this allows sending audio to a retro computer. See later sections for usage information.
