Note:
  1. Values in TYPICAL column are taken at 25°C .
  2. Comparator Ref voltage cannot exceed: (VIN(max) - VIOFF(max) - CMP_5(max) - 50mV) ≥ CMP VREF ≥ (VIN(min) + VIOFF(min) + CMP_5(max) + 50mV).
  3. See Internal Voltage Ref Spec Parameters: VR_9-VR_13.
  4. TRESP is measured from Vin transition to ACOUT (AC direct output) toggle. It takes into account only analog propagation delay.
