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. V
CM COMP
= REF for MAX951/MAX952, and
V
CM 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. V
CM COMP
= REF for
MAX951/MAX952, and V
CM 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 V
SS
.
Note 5: Reference voltage is measured with respect to V
SS
. Contact factory for availability of a 3% accurate reference voltage in the
µMAX package.
