      Hello Alternate,
      

      This part is very old but was an early part to use oversampling but it basically is an R2R type converter. We have nothing like that in the portfolio now. All the converters we have a sigma-delta type. In addition, this part was a 5V part. We have mostly migrated to lower voltages with one exception being the ADAU1966 (without the "A" suffix). However, it is a 16 channel part not stereo.  
      

      

      So what are the requirements for your design? Does it need to be 5V?
      

      Are there only two channels?
      

      Are there latency requirements?
      

      Power dissipation?
      

      What sampling rate?
      

      Any more information you can give would be helpful to find a decent suggestion. It will most likely be a codec of some kind rather than simply a DAC.
