It gives you a clean, pre-set threshold without needing an external reference diode or resistor divider — handy for battery monitors, over-voltage/under-voltage detect, or window comparators on a tight board. The 50mV hysteresis keeps the output from chattering near the trip point, which saves a firmware debounce timer. Temperature grade is -40°C to 85°C, which covers most industrial and automotive-cabin environments. The 80dB CMRR and 80dB PSRR mean the trip point stays put even when your supply is noisy or the common-mode voltage drifts — useful in motor-drive or power-supply feedback loops. ## Sourcing and lifecycle — no LTB worry here No last-time-buy, no end-of-life notice to track. ROHS3 compliant, so it passes the green board requirements without a waiver. ## What the ratings mean for your BOM The 50mV hysteresis is baked in — no external positive feedback resistor needed. That saves two passives and one PCB via per comparator channel. In a high-volume board, that is real BOM cost and placement time. Input offset voltage is 10mV max at 5V supply. ## Integration note — field-swap friendly 8-SOIC, 0.154-inch body width, surface mount. No hot-air station required; a standard soldering iron and tweezers will do the swap on a rework bench. Just watch the quiescent draw if you are replacing a different comparator: at 4µA max, it is one of the lighter loads on the rail.","metaTitle":"MAX981ESA+ Comparator with Voltage Reference, 8-SOIC, Active","metaDescription":"Maxim MAX981ESA+ single comparator with integrated voltage reference, 50mV hysteresis, 4µA quiescent current, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"with Voltage Reference","Package":"Tube","Hysteresis":"50mV","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"80dB CMRR, 80dB PSRR","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-SOIC","Current - Quiescent (Max)":"4µA","Voltage - Input Offset (Max)":"10mV @ 5V","Voltage - Supply, Single/Dual (±)":"2.5V ~ 11V, ±1.25V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.05","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.05000","currency":"USD"},{"qty":10,"price":"$5.43300","currency":"USD"},{"qty":25,"price":"$5.13600","currency":"USD"},{"qty":100,"price":"$4.45110","currency":"USD"},{"qty":250,"price":"$4.22280","currency":"USD"},{"qty":500,"price":"$3.78912","currency":"USD"},{"qty":1000,"price":"$3.19564","currency":"USD"},{"qty":2500,"price":"$3.03586","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX971-MAX984.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is there a pin-compatible alternative to MAX981ESA+?","answer":"The MAX981 family shares the same pinout and function.
