Nominally 1 kΩ to DBGND (may be omitted if data clock output is unused).
SDO is output in 4-wire SPI mode and three-state in 3-wire SPI mode. If SPI is
disabled (SPI_DIS = ADVDD), the alternate pin function is SYNCALRM output.
SDIO is input only in 4-wire SPI mode and bidirectional in 3-wire SPI mode.
If SPI is disabled (SPI_DIS = ADVDD), the alternate pin function is SYNCUPD.
Bypass with 0.1 μF to AGND1. Use the buffer amp to drive external circuitry.
Limit the output current to 1 μA. Apply an external reference to this pin.
Nominally 2 kΩ to AGND1 for 20 mA full-scale output (internal reference).
If SPI is disabled, tie the pin to ADVDD to enable SDR. Otherwise, tie to
ADGND.
Tie the pin to ADVDD to disable SPI; otherwise, tie to ADGND.

Analog Ground. Serves as an
electrical connection to the
substrate of the die and should be
connected to ground for electrical
and thermal purposes.
