In a battery-powered sensor node that sleeps 99% of the time, this comparator does not force a larger battery or a load-switch to disconnect it between readings. The integrated voltage reference eliminates an external reference IC and its associated bias current, so the total comparator + reference draw stays under 1 µA. On a board where every microamp is budgeted, that saves a component and a PCB trace. ## Supply range and output flexibility The CMOS output option gives rail-to-rail swing when the load is on the same supply. 4 mV of built-in hysteresis prevents output chatter when the input signal crosses the threshold slowly — a thermistor voltage ramping over seconds will not cause the output to oscillate at the transition point. ## Package and temperature grade for field deployment Housed in a SOT-23-5 package, the MAX920EUK fits the same footprint as many generic single comparators — a drop-in replacement candidate on boards that originally used a different part with the same pinout. ## Lifecycle and compliance reality One catch: this part is marked RoHS non-compliant. If your BOM requires RoHS-10 (EU 2015/863), this part does not meet it. Check your exemption or plan for a lead-free alternative — the Beyond-the-Rails family includes RoHS-compliant siblings with the same pinout.","metaTitle":"MAX920EUK Analog Devices Comparator, 4mV Hysteresis","metaDescription":"MAX920EUK comparator with integrated voltage reference, 800nA quiescent current, 1.8V-5.5V supply, open-drain/CMOS output.
