This eliminates the pull-up resistor an open-collector comparator would need, simplifying layout and reducing component count on dense boards. With a quiescent current of 80µA max, this part fits into battery-powered and low-power designs where every microamp counts. The 210ns typical propagation delay is fast enough for many control-loop and signal-conditioning applications, though not intended for high-speed RF or GHz-class switching. The operating temperature range of -40°C to 85°C covers industrial environments, outdoor telecom cabinets, and automotive cabin applications without needing a wider-temperature variant. The 80dB CMRR and PSRR provide decent rejection of common-mode and supply noise for a general-purpose comparator in mixed-signal systems. ## Package and footprint Housed in a 5-pin SOT-23 (SOT-753) package, the MAX987EUK is a compact surface-mount part suited for space-constrained PCBs. The SOT-23 footprint is widely used and easy to hand-assemble or reflow in production.","metaTitle":"MAX987EUK General Purpose Comparator, Rail-to-Rail, SOT-23-5","metaDescription":"MAX987EUK general purpose comparator from Maxim Integrated.

The MAX987EUK (Bulk) ships in tubes or trays, while the +T variant comes on a reel. Electrically they are identical."},{"question":"Can MAX987EUK be used as a direct replacement for MAX987ESA?","answer":"MAX987ESA is an 8-pin SOIC package; MAX987EUK is a 5-pin SOT-23. They are not pin-compatible — the die and electrical specs are similar, but the pinout and footprint differ. Verify the PCB layout before substituting."},{"question":"Can MAX987EUK be used in a 3.3V system?","answer":"Yes, the 2.5V to 5.5V single-supply range includes 3.3V. The rail-to-rail output swings to within millivolts of the 3.3V rail, so it interfaces directly with 3.3V logic inputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX987EUK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX987EUK when reusing this data.
