That means one less external reference IC on the board and a simpler BOM for threshold-detection circuits. The 72 µA max quiescent current keeps the power budget tight in battery-powered sensor nodes. Propagation delay is 450 ns max — fast enough for overcurrent or zero-crossing detection in a 100 kHz switching loop, but not for GHz-level comparators. The ±3 mV internal hysteresis prevents output chatter on slow-moving inputs near the threshold. ## Signal-chain fit and output drive Output is CMOS push-pull rail-to-rail with TTL compatibility, so it drives logic inputs directly without a pull-up resistor. Sinks or sources 8 mA typical — enough to drive a small LED or a gate input, but plan a buffer for heavier loads. Input offset voltage is 5 mV max at 5 V — acceptable for threshold detection but not for precision window comparators without calibration. CMRR and PSRR are both 80 dB typical, giving decent rejection of common-mode and supply noise. In a noisy industrial environment, keep the supply bypassed with 0.1 µF close to the pin. ## Temperature range and compliance Not qualified to AEC-Q100, so avoid under-hood automotive designs without additional screening. Lifecycle status is Active per Analog Devices. RoHS non-compliant — the part contains lead (Pb) above the exemption threshold. If your assembly line is RoHS-exempt or you hold a waiver, this is fine; otherwise, flag it for the compliance team.","metaTitle":"MAX9051AEUT Analog Devices Comparator, 450ns, SOT-23-6","metaDescription":"MAX9051AEUT single comparator with precision voltage reference, 450ns propagation delay, 72µA quiescent, SOT-23-6.
