Hi,

Could you please tell us the resolution of the DACs which are built into TLV320DAC3203 since we can not find this information in the data sheet?

The typical SNR is 100dB so the typical effective number of bits of resolution is approx. 16.

Hi Dominik-san,

Thank you for your quick response.
Does this part adopt the 24-bit resolution as the DAC architecture although the ENOB is approximately 16-bit as the DAC performance?

Best Regards,

The part uses 32-bits resolution in the digital domain. The dynamic range, however, limits the effective resolution to ~16 Bits.
