For a new project I’m looking for a DAC with at 24bit/192kHz that sounds good but is also easy to implement. Therefore, I did some research on the DACs available on the market. This is not an exhaustive list, there are much more ICs available. This is just a personal selection of the DACs I found most interesting.
All of the DACs support I2S input data, most of them also support other data format. All data should only give you a first impression. I do not guarantee, that the data is correct. Have a look at the datasheet! The prices are manufacturer prices for 1000 units. If you want to buy only a few pieces for DIY use, the prices are usually much higher. But this is not a problem, because the costs of the DAC chip are only a minor part in the overall costs of a DIY project.

An alternative to traditional DACs are CODEC chips. These chips often have their own clock that can be asynchronous to the input signal. Sometime a PLL synchronizes to an external bit clock. While these ICs may not provide the lowest jitter, often there are an interesting option.
