10 / 96 page  ASAHI KASEI [AK4645] MS0543-E-00 2006/09 - 10 - Parameter min typ max Units Mono Input: MIN pin (AIN3 bit = “0”; External Input Resistance=20kΩ) Maximum Input Voltage (Note 18) - 1.98 - Vpp Gain (Note 19) MIN LOUT/ROUT LOVL bit = “0” −4.5 0 +4.5 dB LOVL bit = “1” - +2 - dB MIN HPL/HPR HPG bit = “0” −24.5 −20 −15.5 dB HPG bit = “1” - −16.4 - dB Stereo Input: LIN2/RIN2/LIN4/RIN4 pins; LIN3/RIN3 pins (AIN3 bit = “1”) Maximum Input Voltage (Note 20) - 1.98 - Vpp Gain LIN/RIN LOUT/ROUT LOVL bit = “0” −4.5 0 +4.5 dB LOVL bit = “1” - +2 - dB LIN/RIN HPL/HPR HPG bit = “0” −4.5 0 +4.5 dB HPG bit = “1” - +3.6 - dB Full-differential Mono Input: IN4+/ − pins (L4DIF bit = “1”) Maximum Input Voltage (Note 21) - 3.96 - Vpp Gain IN4+/ − LOUT/ROUT LOVL bit = “0” −10.5 −6 −1.5 dB (LODIF bit = “0”) LOVL bit = “1” - −4 - dB IN4+/ − LOP/LON LOVL bit = “0” −4.5 0 +4.5 dB (LODIF bit = “1”, Note 22) LOVL bit = “1” - +2 - dB IN4+/ − HPL/HPR HPG bit = “0” −10.5 −6 −1.5 dB HPG bit = “1” - −2.4 - dB Power Supplies: Power-Up (PDN pin = “H”) All Circuit Power-up: AVDD+DVDD+TVDD (Note 23) - 16 24 mA HVDD: HP-Amp Normal Operation No Output (Note 24) - 5 8 mA Power-Down (PDN pin = “L”) (Note 25) AVDD+DVDD+TVDD+HVDD - 1 100 µA 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. |
