Low-Cost Stereo Audio DAC
ELECTRICAL CHARACTERISTICS (continued)
Note 1: 100% production tested at T
Note 2: 0.5 LSB of triangular PDF dither added to data.
Note 3: Guaranteed by design, not production tested.
Note 4: PSRR test block diagram shown in Figure 1 denotes the test setup used to measure PSRR.
Note 5: Volume ramping interval starts from establishment of a valid MCLK to LRCLK ratio. Total time is proportional to the sample
Note 6: In external SCLK mode, LRCLK duty cycles are not limited, provided all data formatting requirements are met. See Figure 4.
Note 7: The LRCLK duty cycle must be 50% ±1/2 MCLK period in internal SCLK mode.
Note 8: The SCLK/LRCLK ratio can be set to 32, 48, or 64, depending on the MCLK/LRCLK ratio selected. See Figure 4.
