Table 2-37 • Recommended Resistor for Different Current Range Measurement
Figure 2-74 • Negative Current Monitor
Terminology
The accuracy of Fusion Current Monitor is ±2 mV minimum plus 5% of the differential voltage at the
input. The input accuracy can be translated to error at the ADC output by using
the gain of the Current Monitor Circuit, as described in the
bit mode, N = 8, V
2 LSBs.
