UNITS
Note 1: Devices are 100% production tested at T A = +25°C. All temperature limits are guaranteed by design.
Note 2: Input Offset Voltage is defined as the center of the input-referred hysteresis zone. Specified for V
CM
= 0. See Figure 1.
Note 3: Trip Point is defined as the input voltage required to make the comparator output change state. The difference
between upper (V
TRIP
+) and lower (V
TRIP
-) trip points is equal to the width of the input-referred hysteresis zone (V
HYST
).
Specified for an input common-mode voltage (V
CM
) of 0. See Figure 1.
Note 4: Inferred from the CMRR test. Note that a correct logic result is obtained at the output, provided that at least one input is
within the V
CMR
limits. Note also that either or both inputs can be driven to the upper or lower absolute maximum limit with-
out damage to the part.
Note 5: Tested over the full-input voltage range (V
CMR
).
Note 6: Differential Propagation Delay is specified as the difference between any two channels in the MAX9107/MAX9108 (both
outputs making either a low-to-high or a high-to-low transition).
Note 7: Propagation Delay Skew is specified as the difference between any single channel’s output low-to-high transition (t
PD
+)
and high-to-low transition (t PD -).
Note 8: Latch specifications apply to MAX9109 only. See Figure 2.
