Parameter NumberSymbolCharacteristicsMin.Typ.Max.UnitsConditions
CMP_1VIOFF_00Input Offset Voltage-1616mVComparator reference voltage = AVDD/2
CMP_4VINInput Voltage RangeAVSSAVDDmVWith respect to GND and AVDD
CMP_5VHYST_00Input Hysteresis Voltage15mVComparator reference voltage = AVDD/2
CMP_15TRESPSS(2)Small Signal Response Time140160nsComparator reference voltage = AVDD/2, input step of 50 mV with Input overdrive = ± 15 mV
CMP_19COUTVALComparator Enabled to Output Valid10msComparator module is configured before enabling it
CMP_21ACIREFComparator Internal Band Gap Voltage Reference1.2VAVDD = 3.3V, T = 25°C
CMP_23CVREFRNGComparator Voltage Reference Input Range(1)(1)V
CMP_25FGCLK_ACAnalog comparator peripheral module clock freqFCLK_49MHz
Note:
  1. Comparator reference voltage cannot exceed:
    (VIN(maximum)VIOFF(maximum)CMP_5(maximum)50mv)CMP_23(VIN(minimum)+abs(VIOFF(minimum))+CMP_5(maximum)+50mv).
  2. TRESP is measured from VIN transition to ACOUT toggle (AC direct output accessible by setting COMPCTRLn.OUT[1:0]). It takes into account only analog propagation delay.
