Hi-speed comparator ICs offer fast propagation delay for lidar, ToF apps
The single-supply devices are compatible with the outputs of several widely used high-speed transimpedance amplifiers, such as the MAX40658, due to their input common-mode range of 1.5 V to VDD+0.1 V. Both the MAX40025 and MAX40026 run from a supply voltage of 2.7 V to 3.6 V.
These ICs can also interface with many modern FPGAs and CPUs since the devices’ output stage is specified for LVDS. This capability enables the comparators to help minimize power dissipation (which aids in system optimization), and complementary outputs help in the suppression of common-mode noise on each output line. Compared to single-ended outputs, the devices’ fully differential LVDS outputs deliver the high-speed digital signaling and reduced EMI necessary for a variety of low-noise, high-performance designs.
Maxim’s MAX4002x comparators are available in a space-saving, compact, 1.218 mm × 0.818 mm WLP package (MAX40025) or an AEC-Q100 automotive qualified 2 mm × 2 mm TDFN package (MAX40026). For development, Mouser is also stocking the MAX40025EVKIT evaluation kit with layout options that allow engineers to easily modify the input termination.
The MAX4002x comparators address the needs of many automotive applications such as lidar and radar environment recognition, sonar; and ToF sensors. Other fields of applications include high-speed differential line receivers; high-speed triggering in oscilloscopes; and communications equipment.
