Its 40 ns propagation delay makes it fast enough for overcurrent detection, zero-crossing sensing, and high-speed window comparators in industrial control loops. The 1.5 mV of built-in hysteresis eliminates output chatter on slowly moving or noisy input signals without adding external positive feedback resistors — a clean layout advantage on a two-layer board. Outputs are CMOS push-pull or TTL-compatible, so the comparator drives logic inputs directly without a pull-up resistor. Supply range spans 2.7 V to 5.5 V. ## Supply voltage and quiescent current — fit for battery and line-powered systems The comparator operates from a single supply as low as 2.7 V. Maximum quiescent current is 300 µA per device. ## Input offset and CMRR — precision for threshold detection Maximum input offset voltage is 2 mV at 5 V. Common-mode and power-supply rejection are both 81.94 dB typical.","metaTitle":"MAX9142ESA+T Comparator, 40ns, 2.7-5.5V, 8-SOIC","metaDescription":"MAX9142ESA+T dual general-purpose comparator from Analog Devices. 40ns propagation delay, 1.5mV hysteresis, CMOS/TTL output.
