(2) Pins 34-37 (MDI, MC, ML, RST). (3) Analog performance specifications are tested with a Shibasoku #725 THD Meter with 400Hz HPF on, 30kHz LPF on, average mode with 20kHz bandwidth limiting. The load connected to the analog output is 5k Ω, or larger, via capacitive loading. (4) Conditions in 192kHz operation are: system clock = 128f S, DAC3 through DAC6 disabled in Register 8, and oversampling rate = 64fS in Register 12. (5) CLKO is disabled.
