Note 15. INTL1/2, INTR1/2, EXTL1/2, EXTR1/2 pins
Note 16. PRELN1/2, PRERN1/2 pins. Gain=0dB, +20dB: 3.5kΩ ± 30%; Gain=+18dB: 4.4kΩ ± 30%, Gain=+24dB:
Note 17. When the output current is 0mA, the output voltage of MPWR pin is typically (MVDD – 1.1) V at MVDD=3.0V
Note 18. Input voltages are proportional to AVDD voltage.
Note 19. Input from LIN, RIN pins. FB = “1”, IVOL=0dB.
Note 20. Input from INTL1/2, INTR1/2, EXTL1/2 or EXTR1/2 pins. Pre-Amp Gain = + 24dB, PRE bit = “1”, FB bit =
