It delivers push-pull, rail-to-rail output with a 228 ns max propagation delay, drawing only 55 µA quiescent current. The 4 mV internal hysteresis cleans up noisy edges without external feedback resistors. Supply range from 2.5 V to 5.5 V lets it run off a 3.3 V or 5 V rail directly, and the -40°C to 125°C operating range means it can sit in an engine bay or an outdoor sensor pod without a second thought. ## 228 ns propagation delay — what it means for your signal chain A 228 ns max delay is fast enough for most threshold-detection and zero-crossing circuits in motor drives, overcurrent latches, or level translators. It is not a high-speed data comparator — you would not use it for gigabit clock recovery — but for industrial sensor conditioning and power-supply fault detection it leaves plenty of timing margin. The 100 dB CMRR and PSRR keep the threshold stable even when the supply rail bounces or the input common-mode voltage shifts. ## 55 µA quiescent current — field-friendly power budget At 55 µA max quiescent, this comparator sips power. In a battery-powered sensor node or a portable instrument, that current is negligible next to the MCU and radio. The input bias current is a mere 0.008 µA at 5 V, so you can use high-value resistive dividers without worrying about offset errors. The 1 mV max input offset voltage is tight enough for precision threshold comparisons — think window comparators or battery undervoltage lockout. ## Package and footprint — SC-70-5 is the one to know The MAX9031AXK+T comes in an SC-70-5 package (also known as SOT-353). It is a five-pin surface-mount part with 0.65 mm pitch — small enough for dense layouts but still hand-solderable with a fine tip and steady hands. If you are prototyping, the Cut Tape (CT) option lets you buy singles; production runs use Tape & Reel (TR). The part is ROHS3 compliant, so no lead-free process headaches. ## Lifecycle and sourcing — active, no LTB worry The MAX9031AXK+T carries an Active lifecycle status from Maxim Integrated (now part of Analog Devices). That means no last-time-buy notice, no end-of-life clock ticking. For a BOM line that needs to run for several years, this part is a safe choice.","metaTitle":"MAX9031AXK+T General Purpose Comparator, 228ns, SC-70-5","metaDescription":"MAX9031AXK+T single general-purpose comparator with 228ns propagation delay, 55µA quiescent current, push-pull output, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"General Purpose","Package":"Tape & Reel (TR); Cut Tape (CT)","Hysteresis":"4mV","Output Type":"Push-Pull, Rail-to-Rail","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"100dB CMRR, 100dB PSRR","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C","Propagation Delay (Max)":"228ns","Supplier Device Package":"SC-70-5","Current - Quiescent (Max)":"55µA","Current - Input Bias (Max)":"0.008µA @ 5V","Voltage - Input Offset (Max)":"1mV @ 5V","Voltage - Supply, Single/Dual (±)":"2.5V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.40000","currency":"USD"},{"qty":10,"price":"$1.25100","currency":"USD"},{"qty":25,"price":"$1.18760","currency":"USD"},{"qty":100,"price":"$0.97570","currency":"USD"},{"qty":250,"price":"$0.91204","currency":"USD"},{"qty":500,"price":"$0.80598","currency":"USD"},{"qty":1000,"price":"$0.63630","currency":"USD"},{"qty":2500,"price":"$0.59388","currency":"USD"},{"qty":5000,"price":"$0.56419","currency":"USD"},{"qty":12500,"price":"$0.54298","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX9030-MAX9034.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to MAX9031AXK+T?","answer":"Pin-compatible alternatives within the same family include the MAX9030 and MAX9032 series from Maxim.
