Note: Comparator Ref voltage cannot exceed: (VIN(max) - VIOFF(max) - CMP_5(max) - 50mV) ≥ C_VREFRNG ≥ (VIN(min) + abs(VIOFF(min)) + CMP_5(max) + 50mV). TRESP_SS is measured from VIN transition to ACOUT toggle (AC direct output accessible by setting COMPCTRLn.OUT[1:0]=0x1). It takes into account only analog propagation delay.
