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

Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Package Information 12 TDFN Package Code TD1232MY+1 Outline Number 21-100369 Land Pattern Number 90-100136 Thermal Resistance, Four-Layer Board: Junction-to-Ambient ( ) 62.75C/W JA Junction-to-Case Thermal Resistance ( ) 8.27C/W JC For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
