(Notes) *1: I: Input terminal, O: Output terminal, A: Analog terminal, O/D: Open/Drain output terminal
*2: PVDD should be connected each other on a board.
*3: GND should be connected each other on a board.
*4: Each output terminal with the same name (OUTPR, OUTMR, OUTPL, and OUTML) should be connected on a
board.
*5: Don't use the terminal AVDD to apply “H” level to the terminal SLEEPN.
When the terminal SLEEPN is "L" level, the terminal AVDD is not supplied.
