Its 5.5ns maximum propagation delay makes it suitable for timing-critical threshold detection, line receivers, zero-crossing detectors, and pulse-width discriminators where the output must settle before the next clock edge. The latch input freezes the output state, allowing the comparator to sample an analog level and hold it for subsequent digital capture — useful in sampled-data systems and peak detectors. ## What the key ratings mean for your BOM Complementary, TTL outputs drive standard 5V or 3.3V logic families directly. The 85dB CMRR and 73dB PSRR mean the comparator rejects common-mode noise on the inputs and supply ripple — important when the part sits near a switching regulator or in a motor-drive environment where ground bounce is present. Single-supply operation from 3V to 5V eliminates the need for a negative rail, simplifying the power tree. The 10mA quiescent current (max) is modest for a 5.5ns comparator — the speed comes from the process, not from burning extra bias current. ## Industrial temperature range — where it fits Rated for -40°C to 85°C, this part is qualified for industrial environments: factory-floor sensors, outdoor telecom base stations, automotive cabin electronics, and test equipment that sees temperature cycling. The 8-SOIC package (3.90mm width) is a standard footprint for mixed-signal boards, compatible with automated assembly lines.","metaTitle":"ADI AD8611ARZ-REEL7 Comparator with Latch, 5.5ns, 8-SOIC","metaDescription":"ADI AD8611ARZ-REEL7 single comparator with latch, 5.5ns propagation delay, complementary TTL output, 85dB CMRR, 3-5V supply, -40 to 85°C, ROHS3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"with Latch","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Complementary, TTL","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"85dB CMRR, 73dB PSRR","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C","Propagation Delay (Max)":"5.5ns","Supplier Device Package":"8-SOIC","Current - Quiescent (Max)":"10mA, 4mA","Current - Input Bias (Max)":"6µA @ 5V","Voltage - Input Offset (Max)":"7mV @ 5V","Voltage - Supply, Single/Dual (±)":"3V ~ 5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.89","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.89000","currency":"USD"},{"qty":10,"price":"$6.22200","currency":"USD"},{"qty":25,"price":"$5.93240","currency":"USD"},{"qty":100,"price":"$5.15100","currency":"USD"},{"qty":250,"price":"$4.91944","currency":"USD"},{"qty":500,"price":"$4.48540","currency":"USD"},{"qty":1000,"price":"$4.09500","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/AD8611_8612.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the propagation delay of AD8611ARZ-REEL7?","answer":"The maximum propagation delay is 5.5ns.
