MAX9015–MAX9020 SOT23, Dual, Precision, 1.8V, Nanopower Comparators With/Without Reference Note 1: All devices are 100% tested at TA = +25°C. Specifications over temperature (TA = TMIN to TMAX) are guaranteed by design, not production tested. Note 2: VOS is defined as the center of the hysteresis band at the input. Note 3: The hysteresis-related trip points are defined as the edges of the hysteresis band, measured with respect to the center of the band (i.e., VOS) (Figure 1). Note 4: Specified with an input overdrive (VOVERDRIVE) of 100mV, and a load capacitance of CL = 15pF. VOVERDRIVE is defined above and beyond the offset voltage and hysteresis of the comparator input.
