APPLICATION INFORMATION

Figure 10 shows each external component.

Figure 10. Application Configuration

NOTE

In the case of an Open Drain Active Low configuration, an external pull-up resistor is

required on the OUT terminal.

Changes to the ranges stated in Table 1 will impact the accuracy of the cell

measurements.
