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. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 1:
Supply current is tested with COMPIN+ = (REF - 100mV) for MAX951/MAX952, and COMPIN+ = 0 for MAX953/MAX954.
Note 2:
Input Offset Voltage is defined as the center of the input-referred hysteresis. VCM COMP
= REF for MAX951/MAX952, and
VCM COMP = 0 for MAX953/MAX954.
Note 3:
Trip Point is defined as the differential input voltage required to make the comparator output change. The difference
between upper and lower trip points is equal to the width of the input-referred hysteresis. VCM COMP
= REF for MAX951/
MAX952, and VCM COMP = 0 for MAX953/MAX954.
Note 4:
For MAX951/MAX952, input leakage current is measured for COMPIN- at the reference voltage. For MAX953/MAX954,
input leakage current is measured for both COMPIN+ and COMPIN- at VSS.
Note 5:
Reference voltage is measured with respect to V
SS
. Contact factory for availability of a 3% accurate reference voltage in
