MAX40027
Dual 280ps High-Speed Comparator, Ultra-Low
Dispersion with LVDS Outputs
General Description
Benefits and Features
The MAX40027 is a single-supply, dual high-speed com-
parator with a typical propagation delay of 280ps. The
overdrive dispersion is extremely low (25ps, typ.), making
these comparators ideal for time-of-flight, distance-mea-
surement applications.
● Fast Propagation Delay: 280ps, Typ
● Low Overdrive Dispersion: 25ps (V
● Supply Voltage 2.7V to 3.6V
= 10mV to 1V)
OD
● 45.9mW at 2.7V Supply (Each Comparator)
● Power-Efficient LVDS Outputs
● -40°C to +125°C Temperature Range
● Automotive AEC-Q100 Qualified
● Small, 3mm x 2mm TDFN Package with Side-Wettable
Flanks
The input common mode range of 1.5V to V
+ 0.1V
DD
is compatible with the output swings of several widely
used high-speed trans-impedance amplifiers, such as the
MAX40658, MAX40660, and MAX40661.
The output stage is LVDS (Low-Voltage Differential Sig-
naling), which helps to minimize power dissipation and in-
terfaces directly with many FPGAs and CPUs. Comple-
mentary outputs help in suppression of common-mode
noise on each output line.

The MAX40027 is offered in a tiny, space-saving, 3mm x
2mm, 12-pin TDFN package with side-wettable flanks, and
meets AEC-Q100 automotive qualification requirements.
The MAX40027 operates over the -40°C to +125°C tem-
perature range and runs from a 2.7V to 3.6V supply volt-
age.
