Using external voltage refer- ence 0 µA IACMPREF Current consumption of in- ternal voltage reference Internal voltage reference 5 µA Single ended 10 mV VACMPOFFSET Offset voltage Differential 10 mV VACMPHYST ACMP hysteresis Programmable 17 mV CSRESSEL=0b00 in ACMPn_INPUTSEL 39 kOhm CSRESSEL=0b01 in ACMPn_INPUTSEL 71 kOhm CSRESSEL=0b10 in ACMPn_INPUTSEL 104 kOhm RCSRES Capacitive Sense Internal Resistance CSRESSEL=0b11 in ACMPn_INPUTSEL 136 kOhm The total ACMP current is the sum of the contributions from the ACMP and its internal voltage reference as given in Equation 3.1 (p. 49) . IACMPREF is zero if an external voltage reference is used. Total ACMP Active Current IACMPTOTAL = IACMP + IACMPREF (3.1) |
