(1) This parameter covers one single ESI comparator; either ESI AFE1 comparator or ESI AFE2 comparator.
(2) The comparator output is reliable when at least one of the input signals is within the common mode input voltage range.
(3) Calculated using the box method: (MAX(–40°C to 85°C) – MIN(–40°C to 85°C)) / MIN(–40°C to 85°C) / (85°C – (–40°C))
(4) Calculated using the box method: ABS((Voffset_Vcc_max – Voffset_Vcc_min)/(Vcc_max – Vcc_min))
