MAX40025A/MAX40025C/
MAX40026
280ps High-Speed Comparator, Ultra-Low
Dispersion with LVDS Outputs
General Description
Benefits and Features
The MAX40025 and MAX40026 are single-supply, high-
speed comparators with a typical propagation delay of
280ps. The overdrive dispersion is extremely low (typical
25ps), making these comparators ideal for time-of-flight
distance measurement applications.
● Fast Propagation Delay: 280ps, Typ
● Low Overdrive Dispersion: 25ps (V
● Supply Voltage 2.7V to 3.6V
● 39.4mW at 2.7V Supply
= 10mV to 1V)
OD
● Power-Efficient LVDS Outputs
● -40°C to +125°C Temperature Range
● Automotive AEC-Q100 Qualified (TDFN-8 Version)
● Internal 1.5mV Hysteresis: MAX40026
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.
● Internal 2.5mV Hysteresis: MAX40025A
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 MAX40025 is offered in a space-saving, tiny,
1.218mm x 0.818mm, 6-bump wafer-level package
(WLP), while the MAX40026 is available in a 2mm x 2mm
8-pin TDFN side-wettable package and meets AEC-Q100
automotive qualification requirements. The MAX40025/
MAX40026 operate over -40°C to +125°C temperature
range and run from a single supply voltage of 2.7V to 3.6V.
