It operates from a 1.8V to 5.5V supply rail, drawing a maximum quiescent current of 1.6µA. The open-drain output with 4mV hysteresis suits it for low-frequency threshold sensing — temperature alarms, undervoltage lockout, or battery-monitor trip points where the 120µs propagation delay is fast enough. Output sink capability is 50mA typical, enough to drive a small relay coil or an LED indicator directly. ## Lifecycle and sourcing reality The MAX918ESA+ carries an Active lifecycle status with ROHS3 compliance. For small quantities or prototype builds, the same channel applies — no minimum order threshold beyond what the distributor sets.","metaTitle":"MAX918ESA+ Comparator with Voltage Reference, 1.6µA, 8-SOIC","metaDescription":"MAX918ESA+ single comparator with integrated voltage reference, 1.8V-5.5V supply, 1.6µA quiescent current, 4mV hysteresis, open-drain output.","metaKeywords":null},"attributes":{"series":"Beyond-the-Rails™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"with Voltage Reference","Series":"Beyond-the-Rails™","Package":"Tube","Hysteresis":"4mV","Output Type":"Open-Drain","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"80dB PSRR","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C","Current - Output (Typ)":"50mA","Propagation Delay (Max)":"120µs","Supplier Device Package":"8-SOIC","Current - Quiescent (Max)":"1.6µA","Current - Input Bias (Max)":"0.001µA @ 5V","Voltage - Input Offset (Max)":"5mV @ 5V","Voltage - Supply, Single/Dual (±)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.24000","currency":"USD"},{"qty":10,"price":"$2.90900","currency":"USD"},{"qty":25,"price":"$2.74960","currency":"USD"},{"qty":100,"price":"$2.38310","currency":"USD"},{"qty":250,"price":"$2.26088","currency":"USD"},{"qty":500,"price":"$2.02868","currency":"USD"},{"qty":1000,"price":"$1.71094","currency":"USD"},{"qty":2500,"price":"$1.62539","currency":"USD"},{"qty":5000,"price":"$1.56429","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/93194e4fb077f59abed7b60bb1f4361c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the nearest equivalent to MAX918ESA+?","answer":"The closest sibling is the MAX917ESA+, which differs primarily in hysteresis — the MAX917 has no internal hysteresis (it relies on external feedback), while the MAX918ESA+ has 4mV of built-in hysteresis. If your design needs the internal reference but can add external hysteresis resistors, the MAX917 is pin-compatible. For a drop-in replacement with the same 4mV hysteresis, the MAX918ESA+ is the target."},{"question":"What is the output type and hysteresis of MAX918ESA+?","answer":"Output type is open-drain, and the built-in hysteresis is 4mV. The open-drain output requires a pull-up resistor to the desired logic rail — typically 10kΩ to 100kΩ for low-speed threshold sensing."},{"question":"What is MAX918ESA+'s listed type and series?","answer":"The type is 'with Voltage Reference' — an integrated 1.236V ±1.5% reference is included on-chip.
