Non Oversampling DAC
Back in 2004 I purchased a Non Oversampling (NOS) DAC kit from DiyParadise.
This is based around a Phillips TDA1543 chip.
I built the PCB into a small Hammond enclosure, and used a spare "wall wart" power supply to power it.
It is recommended to power these DACs from a battery, but I wanted the convenience of a mains supply.
I built a pre-regulator stage and added plenty of decoupling, and to my mind it doesn't sound any different to battery power.
Some pics and additional details to follow. (6th July 07)
Update 16th October 2008 - I just noticed I still haven't posted any pics of my DAC.
Watch this space... :)
