Part Number: TLV320DAC23

Customer is looking for a DAC w/headphone amp that meets these requirements -

100+ dB SNR and very low THD

Besides TLV320DAC3203 and TLV320DAC23, do we have other solutions to recommend?

Hi Jia Jia,

These are the better SNR DACs with integrated HP amplifier.

Hi Ivan - thanks for the response. Just to confirm, these 2 parts are the best options? Do we have higher SNR options w/int HP amp?

Jia Jia,

These are the best options. You can use the compare tool in DAC products and look for higher SNR: www.ti.com/.../products.html
There are higher SNR DACs but HP amp is not integrated, using an external HP amp and higher SNR DAC could be another option.

Thanks Ivan. Can you recommend some external HP amp + high SNR DAC solutions?

Jia Jia,

For the headphone amp the highest SNR are TPA6140A2/TPA6141A2 (105dB), the next better are TPA6132A2 and TPA6136A2 (100dB).
Regarding the DAC, some of them could be PCM1795/PCM1796/PCM1798 (123dB) or PCM1789 (113dB), I selected these based on reduced channel count. However you could ask for recommendations based on your overall system through the Converters Forum as we're supporting only the DACs with intergrated HP amp.
