The On Board I
Interface
The I
LMV1089 demoboard is located at the header J20 with an
indication ' I2C' printed on the PCB (see Figure 6). The signals
on this header are described in Table 3.
The I
LMV1089 can be accessed is selected with the jumper on
header J17 (see Figure 6).

The supply voltage for the I
be selected with the jumper on J22 (see Figure 6).
With the jumper between pin 2 and pin 3 the I
levels will be related to supply voltage of the LMV1089.
With the jumper between pin 1 and pin 2 the I
levels will be related to the voltage supplied via pin 1 at the
