8 / 64 page  ASAHI KASEI [AK4534] MS0133-E-03 2003/5 - 8 - Parameter min typ max Units Mono Output: RL=10kΩ, DAC → MIX → MOUT2 Output Voltage (Note 13) 1.94 Vpp Load Resistance 10 k Ω Load Capacitance (Note 14) 30 pF Power Supplies Power Up (PDN = “H”) AVDD+DVDD (Note 15) 16 26 mA PVDD 1.2 2 mA HVDD: HP-AMP Normal Operation No Output (Note 16) 6.5 10 mA HVDD: SPK-AMP Normal Operation No Output (Note 17) 9 18 mA Power Down (PDN = “L”) (Note 18) AVDD+DVDD 10 100 µA PVDD 10 100 µA HVDD 10 100 µA Note 4. Output voltage is proportional to AVDD voltage. Vout = 0.75 x AVDD. Note 5. When IPGA Gain is changed, this typical value changes between 8k Ω and 11kΩ. Note 6. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD. Note 7. Output voltage is proportional to AVDD voltage. Vout = 1.2 x AVDD at Full-differential output. Vout = 0.6 x AVDD at Single-end Output Note 8. Output voltage is proportional to AVDD voltage. Vout = 0.582 x AVDD. Note 9. Output voltage is proportional to AVDD voltage. Vout = 0.897 x AVDD at Full-differential output. Note 10. BEEP-AMP can’t output more than this maximum voltage. Note 11. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD. Note 12. When ALC2 Gain is changed, this typical value changes between 22k Ω and 26kΩ. Note 13. Output Voltage is proportional to AVDD voltage. Vout = 0.588 x AVDD. Note 14. When the output pin drives a capacitive load, a resistor should be added in series between the output pin and capacitive load. Note 15. PMMIC=PMADC=PMDAC=PMMO=PMSPK=PMHPL=PMHPR=PMVCM=PMPLL=PMXTL=PMBPM =PMBPS=“1”,MCKO=”1” and Master Mode. AVDD : 10mA (typ.), DVDD : 6mA (typ.) AVDD : 10mA (typ.), DVDD : 4mA (typ.) at MCKO= “0” in Slave Mode Note 16. PMMIC=PMADC=PMDAC=PMMO=PMHPL=PMHPR=PMVCM=PMPLL=PMXTL=PMBPM =PMBPS=“1”, PMSPK=“0”. Note 17. PMMIC=PMADC=PMDAC=PMMO=PMSPK=PMVCM=PMPLL=PMXTL=PMBPM=PMBPS=“1” PMHPL=PMHPR=“0”. Note 18. All digital input pins are fixed to DVDD or DVSS. HPL/HPR pin HP-Amp 47 µF C1 16 Ω C2 > 6.8 Ω Figure 1.
