It integrates four independent comparators with push-pull, rail-to-rail outputs, so no external pull-up resistor is needed — a clean interface to 3.3 V or 5 V logic. The 2.5 V to 5.5 V single-supply range lets it run directly off a 3.3 V or 5 V rail without a secondary regulator, which simplifies the power tree in mixed-voltage designs. The 228 ns maximum propagation delay sets the timing budget for threshold detection, zero-crossing, and overcurrent/overvoltage fault loops. At that speed it handles switching frequencies up to a few hundred kilohertz cleanly — fast enough for most sensor comparators, window detectors, and level translators, but not for high-speed data recovery or GHz-class signal chains. Quiescent current maxes at 55 µA per package (all four channels active), which keeps the power budget tight in battery-operated equipment like portable instruments, remote sensors, and IoT edge nodes. The -40°C to 125°C operating range covers industrial control cabinets, outdoor telecom enclosures, and under-hood automotive electronics — no commercial-grade temperature restriction. ## Key ratings and what they mean for the BOM Propagation delay (228 ns max) is the spec that decides whether this comparator can close a control loop or flag a fault within your timing budget. For a 100 kHz switching power supply, 228 ns adds about 2.3% of the period — acceptable for overcurrent detection but marginal for cycle-by-cycle peak current limiting. For slower signals like temperature thresholds or battery undervoltage locks, it is more than adequate. Input offset voltage is specified at 1 mV max at 5 V, which sets the DC accuracy floor for the threshold. Combined with 4 mV of hysteresis, the comparator resists chatter on slowly moving inputs — useful for noisy environments like motor drives or solenoids. The 0.008 µA max input bias current at 5 V means the source impedance can be tens of kilo-ohms without introducing significant offset error. CMRR and PSRR are both 100 dB typical, giving strong rejection of common-mode noise and supply ripple. In a 12 V system divided down to 3.3 V, a 100 mV ripple on the supply translates to roughly 1 µV of referred offset — negligible for most threshold applications. ## Lifecycle and sourcing reality The MAX9034ASD+ carries an Active lifecycle status per the manufacturer, with ROHS3 compliance. For dual-sourcing resilience, the 14-SOIC footprint is common across several quad comparator families, though no official second-source alternate is listed in the available records.","metaTitle":"MAX9034ASD+ Quad Comparator, 228ns Propagation Delay","metaDescription":"MAX9034ASD+ general-purpose quad comparator from Analog Devices. 228ns max propagation delay, 55µA quiescent current, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"General Purpose","Package":"Tube","Hysteresis":"4mV","Output Type":"Push-Pull, Rail-to-Rail","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"100dB CMRR, 100dB PSRR","Number of Elements":"4","Operating Temperature":"-40°C ~ 125°C","Propagation Delay (Max)":"228ns","Supplier Device Package":"14-SOIC","Current - Quiescent (Max)":"55µA","Current - Input Bias (Max)":"0.008µA @ 5V","Voltage - Input Offset (Max)":"1mV @ 5V","Voltage - Supply, Single/Dual (±)":"2.5V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.59","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.59000","currency":"USD"},{"qty":10,"price":"$2.32900","currency":"USD"},{"qty":25,"price":"$2.19680","currency":"USD"},{"qty":100,"price":"$1.87160","currency":"USD"},{"qty":250,"price":"$1.75740","currency":"USD"},{"qty":500,"price":"$1.53772","currency":"USD"},{"qty":1000,"price":"$1.27412","currency":"USD"},{"qty":2500,"price":"$1.18624","currency":"USD"},{"qty":5000,"price":"$1.14231","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX9030-MAX9034.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum propagation delay of the MAX9034ASD+?","answer":"The maximum propagation delay is 228 ns.
