Current Monitor
Unless otherwise noted, current monitor performance is specified at 25°C with nominal power supply
voltages, with the output measured using the internal voltage reference with the internal ADC in 12-bit
mode and 91 Ksps, after digital compensation. All results are based on averaging over 16 samples.
