(Note 1) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.

MAX9015–MAX9020 SOT23, Dual, Precision, 1.8V, Nanopower Comparators With/Without Reference 5Maxim Integrated 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. Note 5: High current traces should not be routed in the vicinity of or below MAX9018. There is a chance of voltage reference being overloaded resulting in drop of output voltage.
