Power Supplies:
Power-Up (PDN pin = “H”)
All Circuit Power-up:
AVDD+DVDD+TVDD (Note 23)
HVDD: HP-Amp Normal Operation
No Output (Note 24)
Power-Down (PDN pin = “L”) (Note 25)
AVDD+DVDD+TVDD+HVDD
Note 18. Maximum voltage is in proportion to both AVDD and external input resistance (Rin). Vin = 0.6 x AVDD x Rin
/ 20k
Ω
(typ).
Note 19. The gain is in inverse proportion to external input resistance.
Note 20. Maximum Input voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 21. Maximum Input voltage is proportional to AVDD voltage. Vout = (IN4+)
(IN4
) = 1.2 x AVDD (typ). The
signals with same amplitude and inverted phase should be input to IN4+ and IN4
pins, respectively.
Note 22. Vout = (LOP)
(LON) at LODIF bit = “1”.
Note 23. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
PMVCM = PMPLL = MCKO = PMMIN = PMMP = M/S bits = “1”. MPWR pin outputs 0mA.
AVDD=11mA(typ), DVDD=3mA(typ), TVDD=2mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=10mA(typ), DVDD=3mA(typ),
TVDD=0.03mA(typ).
Note 24. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMMIN bits = “1”.
Note 25. All digital input pins are fixed to TVDD or HVSS.
