Note 11. In case of singled-ended mode. Only mixer path of inputting signal is ON. (In case of differential mode, this
value is typically 29μVrms.)
Note 12. PSR is applied to AVDD and PVDD with 100mpVpp sine wave.
Note 13. PSR is applied to SVDD with 0.89Vpp sine wave.
Note 14. In case of single-ended mode. (In case of differential mode, the input signal level is 0.425Vrms. The signals with
amplitude and inverted phase should be input to positive input pin and negative input pin.)
Note 15. In case of single-ended mode. (In case of differential mode, the input signal level is 0.32Vrms. The signals with
amplitude and inverted phase should be input to positive input pin and negative input pin.)
Note 16. In case of single-ended mode. (In case of differential mode, the input signal level is 0.23Vrms. The signals with
amplitude and inverted phase should be input to positive input pin and negative input pin.)
Note 17. In case of singled-ended mode. Only mixer path of inputting signal is ON. (In case of differential mode, this
value is typically 90μVrms. )
Note 18. PSR is applied to AVDD with 100mpVpp sine wave.
Note 19. PSR is applied to SVDD with 100mpVpp sine wave.
Note 20. Average current between SVDD and VSS2 when the SPP and SPN pins are shorted and 0.85Vrms, 1kHz sine
wave is input to the AK4213 in single-ended mode.
Note 21. This is capacitance value between output pin and VSS1. When a capacitor is connected between output pins,
load capacitance for each output pin doubles. Therefore, it is necessary to decide load capacitance in
consideration of these.
Note 22. All Circuits are powered-up.
(PMVCM = PMOSC = PMCP = PMHPL = PMHPR = PMMHL = PMMHR = PMSPK = PMMSP = PMV1 =
PMV2 = PMV3 bits= “1”)
Note 23. Minimum blocks for Headphone-Amp path are powered-up.
(PMVCM = PMOSC = PMCP = PMHPL = PMHPR = PMMHL = PMMHR = PMV1 bits= “1”,
PMSPK = PMMSP = PMV2 = PMV3 bits= “0”)
Note 24. Minimum blocks for Speaker-Amp path are powered-up
(PMVCM = PMOSC = PMCP = PMSPK = PMMSP = PMV1 bits= “1”,
PMHPL = PMHPR = PMMHL = PMMHR = PMV2 = PMV3 bits= “0”)
Note 25. All digital input pins are held at VSS1.
