It is not a high-speed part for RF envelope detection or fast-switching regulators — that would call for a sub-100ns comparator — but for general-purpose threshold monitoring it is well within the timing budget. ## 2µA quiescent current — keeps the power budget lean The quiescent current per comparator is 2µA maximum, which matters when the circuit is always-on — battery-backed alarm thresholds, remote sensor nodes, or energy-harvesting triggers. The low bias current of 0.001µA at 5V means the input impedance is high enough to work directly with high-resistance sensor bridges without loading the signal. ## Built-in 4mV hysteresis — no external feedback network needed The 4mV internal hysteresis eliminates the need for a positive-feedback resistor pair around the comparator to prevent output chatter when the input signal crosses the threshold slowly. That saves two resistors per channel and simplifies the layout — a practical advantage when board space is tight in the SOT-23-8 footprint. ## Active production — no end-of-life concern for new builds The MAX9019EKA+T carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX9019EKA+T General Purpose Comparator, Dual, SOT-23-8","metaDescription":"MAX9019EKA+T dual general-purpose comparator from Maxim's Beyond-the-Rails™ series. 28µs propagation delay, 2µA quiescent current, rail-to-rail CMOS output.","metaKeywords":null},"attributes":{"series":"Beyond-the-Rails™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"General Purpose","Series":"Beyond-the-Rails™","Package":"Tape & Reel (TR); Cut Tape (CT)","Hysteresis":"4mV","Output Type":"CMOS, Push-Pull, Rail-to-Rail","Mounting Type":"Surface Mount","Package / Case":"SOT-23-8","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"80dB PSRR","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C","Current - Output (Typ)":"50mA","Propagation Delay (Max)":"28µs","Supplier Device Package":"SOT-23-8","Current - Quiescent (Max)":"2µA","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":"$2.14","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.14000","currency":"USD"},{"qty":10,"price":"$1.92100","currency":"USD"},{"qty":25,"price":"$1.81240","currency":"USD"},{"qty":100,"price":"$1.54420","currency":"USD"},{"qty":250,"price":"$1.45000","currency":"USD"},{"qty":500,"price":"$1.26876","currency":"USD"},{"qty":1000,"price":"$1.08750","currency":"USD"},{"qty":2500,"price":"$1.08750","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX9015-MAX9020.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the propagation delay of MAX9019EKA+T?","answer":"The maximum propagation delay is 28µs.

The 1.8V to 5.5V supply range covers 3.3V logic rails directly, and the rail-to-rail CMOS output swings to the supply rails, so it interfaces with 3.3V logic without level shifting."},{"question":"Can MAX9019EKA+T be used as a window comparator?","answer":"Yes — the dual comparator in one package is a natural fit for a window comparator. One comparator sets the upper threshold, the other the lower threshold, and the push-pull outputs can be wire-ANDed (with external diodes) to flag when the input is inside or outside the window."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX9019EKAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX9019EKAT when reusing this data.
