Disassembling a retired CD player I recovered some chips with one of them being TDA1311 which is a DAC. It is an eight pin dual in line chip with seven active terminals and one not used. Browsing its data sheet I found there is a striking similarity to DACs discussed in these forums. My pertinent question: Is this chip still useable, for instance, to implement a USB DAC?

A brief look at the datasheet looks a lot like it wants to see Left Justified PCM, 16-bits. A versatile USB board such as: I2SoverUSB - I2S over USB Audio ...could probably provide the needed format.
Yes why not, certainly not the Phiips dac chip of the year -I didn't know that reference- choices are limited as it's an internal I/V i.e. voltage output dac chip. The clock frequency seems to be unusual with 18M hz...you can test it with a good bufer/filter as per datasheet and a filter/oversampling chip before ! 🙂
