SPECIFICATIONS

TA = 25°C, VEE = −3 V, VCCI = 3.3 V, VCCO = 2 V, VTERM = 0 V, VCM = 0 V, VOD = 50 mV. VOD is the input overdrive voltage, for example,

VWIN − VRT = VOD or VWIN − VRB = VOD.

1 Equivalent input bandwidth is calculated with the following formula: BWEQ = 0.22⁄√(TRCOMP2 − TRIN2), where BWEQ is the equivalent bandwidth formula, TRIN is the 20% to

80% transition time of a quasi Gaussian signal applied to the comparator input, and TRCOMP is the effective transition time digitized by the comparator.
