C Address Bit. AD[0] sets the I
2
C address of the device. User-
selectable device address bit, LSB, LSB+1, MSB (see Figure 5).
22 AD1
Programmable I
2
C Address Bit. AD[1] sets the I
2
C address of the device. User-
selectable device address bit, LSB, LSB+1, MSB (see Figure 5).
23 AD2
Programmable I
2
C Address Bit. AD[2] sets the I
2
C address of the device. User-
selectable device address bit, LSB, LSB+1, MSB (see Figure 5).
