1 Equivalent input rise time bandwidth assumes a first-order input response and is calculated by the following formula: BWEQ = 0.22/√ (trCOMP2 – trIN2), where trIN is the

20/80 input transition time applied to the comparator and trCOMP is the effective transition time as digitized by the comparator input.
