DESCRIPTION
Power supply for internal analog circuitry
Connection point for internal reference used by ANA_REG and VCOM filter
capacitors
Voltage regulator derived from AVDD supply (NOTE: This terminal is provided
as a connection point for filtering capacitors for this supply and must not be
used to power any external circuitry)
Connection point for the SPK_OUTA- bootstrap capacitor, which is used to
create a power supply for the high-side gate drive for SPK_OUTA-
Connection point for the SPK_OUTA+ bootstrap capacitor, which is used to
create a power supply for the high-side gate drive for SPK_OUTA
Connection point for the SPK_OUTB- bootstrap capacitor, which is used to
create a power supply for the high-side gate drive for SPK_OUTB-
Connection point for the SPK_OUTB+ bootstrap capacitor, which is used to
create a power supply for the high-side gate drive for SPK_OUTB+
Ground for digital circuitry (NOTE: This terminal should be connected to the
system ground)
Power supply for the internal digital circuitry
Dual function terminal that functions as an I²C data input terminal in I²C Control
Mode or as a Frequency Select terminal when in Hardware Control Mode.
Ground for gate drive circuitry (this terminal should be connected to the system
ground)
Voltage regulator derived from PVDD supply (NOTE: This terminal is provided
as a connection point for filtering capacitors for this supply and must not be
used to power any external circuitry)
Word select clock for the digital signal that is active on the serial port's input
data line
Master Clock used for internal clock tree, sub-circuit/state machine, and Serial
Audio Port clocking
Dual function terminal that functions as an I²C clock input terminal in I²C
Control Mode or configures the device to operate in pre-filter Parallel Bridge
Tied Load (PBTL) mode when in Hardware Control Mode
(1) AI = Analog input, AO = Analog output, DI = Digital Input, DO = Digital Output, P = Power, G = Ground (0V)
