(1)

The I2C address is linked to the selected start-up voltage. The user cannot select the start-up voltage and I2C address independently.

(2)

The user can use the VSEL pin to select which of the four start-up voltages the device uses. For more information, see Table 7-5 and

Table 7-10.

(3)

Contact TI for other start-up voltage or I2C address options

Unless otherwise noted, device variants without I2C operate with the same default settings as device variants

with I2C.
