Description
In past we described an S/PDIF tester, consisting of a special decoder IC with integrated D/A converter. Two implementations of the ‘IEC 60958 audio DAC’ from Philips could be used here: the UDA1350ATS or the UDA1351TS. The latter has a frequency range up to 96 kHz. However, a number of readers were disappointed that this circuit was not accompanied by a PCB design. That is the reason that we present a similar ‘Mini Audio DAC’ here, this time with matching PCB layout. The IC that has been used here, the UDA1351H, belongs to the same family as the aforementioned types, but is packaged in a different housing. The advantage of the SOT307-2 (QFP44) package is that the pins are a little further apart (0.8 mm instead of 0.65 mm), which makes soldering with a normal soldering iron considerably easier. http://www.eeweb.com/blog/extreme_circuits/mini-audio-dac
