That integrated reference is the main event: it saves a board slot and a resistor-divider pair for threshold detection, battery monitoring, or level sensing where you need a stable trip point without external components. The 50 mV of hysteresis gives clean switching on noisy signals — no chatter at the threshold crossing. Quiescent current maxes at 4 µA, which makes this part a fit for battery-powered threshold detectors that spend most of their time asleep. The 12 µs propagation delay is the trade-off: fast enough for a 10 kHz-level signal edge, but not for high-speed PWM feedback or short-pulse fault capture. Output swings CMOS or TTL levels, so it mates directly with a logic input without a pull-up resistor. Supply range covers 2.5 V to 11 V single supply, or ±1.25 V to ±5.5 V dual. Input offset voltage is specified at 10 mV max at 5 V. ## Temperature grade and environment Rated for 0°C to 70°C, the MAX931CSA+ is a commercial-temperature part. That means indoor, climate-controlled equipment — lab instruments, benchtop power supplies, office peripherals, consumer electronics. Not for an automotive cabin, an outdoor telecom cabinet, or an industrial motor-drive enclosure where ambient can push past 70°C. ## Lifecycle and sourcing The MAX931CSA+ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX931CSA+ Comparator with Voltage Reference, 4µA, 8-SOIC","metaDescription":"Maxim MAX931CSA+ single comparator with integrated voltage reference. 4µA quiescent, 12µs propagation delay, 2.5V to 11V supply. 8-SOIC, ROHS3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"with Voltage Reference","Package":"Tube","Hysteresis":"50mV","Output Type":"CMOS, TTL","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":"0°C ~ 70°C","Current - Output (Typ)":"0.015mA @ 5V","Propagation Delay (Max)":"12µs","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":"$6.32","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.32000","currency":"USD"},{"qty":10,"price":"$5.67300","currency":"USD"},{"qty":25,"price":"$5.36320","currency":"USD"},{"qty":100,"price":"$4.64800","currency":"USD"},{"qty":300,"price":"$4.40967","currency":"USD"},{"qty":500,"price":"$3.95678","currency":"USD"},{"qty":1000,"price":"$3.33704","currency":"USD"},{"qty":2500,"price":"$3.17019","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3ff20f9570cb1853014861278f49fdfd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the exact specifications of MAX931CSA+ comparator?","answer":"The MAX931CSA+ is a single comparator with an integrated voltage reference.
