Parameter
Mono Input: MIN pin (AIN3 bit = “0”; External Input Resistance=20kΩ)
Maximum Input Voltage (Note 18)
Gain (Note 19)
Stereo Input: LIN2/RIN2/LIN4/RIN4 pins; LIN3/RIN3 pins (AIN3 bit = “1”)
Maximum Input Voltage (Note 20)
Gain
Full-differential Mono Input: IN4+/− pins (L4DIF bit = “1”)
Maximum Input Voltage (Note 21)
Gain
Power Supplies:
Power-Up (PDN pin = “H”)
Power-Down (PDN pin = “L”) (Note 25)
Note 18. Maximum voltage is in proportion to both AVDD and external input resistance (Rin). Vin = 0.6 x AVDD x Rin
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
Note 22. Vout = (LOP) − (LON) at LODIF bit = “1”.
Note 23. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
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.
