Note 1: Data in “Typ” column is at 3.3V, +25°C unless otherwise stated.
2: Resistances can vary by ±10% between op amps.
3: Device is functional at V
BORMIN < VDD < VDDMIN, but will have degraded performance. Device functionality
is tested, but not characterized. Analog modules: ADC, op amp/comparator and comparator voltage
reference, will have degraded performance. Refer to Parameter BO10 in Table 33-12 for the minimum and
maximum BOR values.
