Note 11. Maximum output voltage is (0.6 x AVDD) Vpp.
Note 12. Load resistance is the value of “Rf + Ri”. (Refer to Figure 12)
Note 13. When the output pin drives some capacitive load, some resistor should be added in series between output pin and
capacitive load.
Note 14. When the output current is 0mA, the output voltage of MPWR pin is typically (MVDD – 1.2) V at MVDD=2.8V
and typically (MVDD-1.4) V at MVDD=4.5V.
When the output current is 3mA, the output voltage of MPWR pin is typically (MVDD – 1.5) V at MVDD=2.8V
and typically (MVDD-1.7) V at MVDD=4.5V.
Note 15. Input voltages are proportional to AVDD voltage.
LIN1, RIN1, LIN2, RIN2 = (0.62 x AVDD) Vpp
INTL, INTR, EXTL, EXTR = (0.0013 x AVDD) Vpp
Note 16. Input from LIN1, RIN1, LIN2 or RIN2 pins. IVOL=0dB.
Note 17. Input from INTL, INTR, EXTL or EXTR pins. Pre-Amp Gain = + 23.9dB, PRE = “1”, IVOL = +29.625dB
External resistor of Pre-Amp is “Rf = 10k
, Ri = 680
”. (Refer to Figure 12)
Note 18. Input from INTL, INTR, EXTL or EXTR pins. Pre-Amp Gain = + 23.9dB, PRE = “1”, IVOL = +0dB
External resistor of Pre-Amp is “Rf = 10k
, Ri = 680
”. (Refer to Figure 12)
