The Dac One is a modern high precision replacement for old dacs very often used in "non oversampled" systems
like the old TDA 1543 and TDA 1541. It is not a pin compatible replacement but a way to build up a converter
system which can meet the best systems today in terms of sound quality.
The Dac One is build up around a fast 16 bits and very accurate R2R ladder network. To match this ladder network
to real audio formats, fast glue logic is added and makes the dac compatible with RJ16, RJ24 and I2S standards.
The ladder network is designed as a current output device so to get a voltage out an I/V converter is needed.
Depending on designers needs the Dac One is available in both current and voltage output versions.
