NOTES: (1) Refer to the System Clock section of this data sheet. (2) An external buffer is recommended. (3) Dynamic performance specifications are tested with 20kHz low-pass
filter and THD+N specifications are tested with 30kHz LPF, 400Hz HPF, Average Mode. (4) Dynamic performance specifications are tested with HDCD gain scaling set to analog
gain scaling. (5) SNR is tested with infinite zero detection off. (6) Output level is for sine wave. DAC outputs 0.64 V
