Each of the two comparators includes 50 mV of built-in hysteresis, which eliminates output chatter on slow-moving input signals without external positive feedback resistors. The CMOS/TTL-compatible outputs sink or source directly to logic inputs. Supply range spans 2.5 V to 11 V single supply (or ±1.25 V to ±5.5 V dual). Maximum quiescent current is 6 µA. Packaged in an 8-pin DIP (0.300\" width, 7.62 mm pitch) with through-hole mounting — a breadboard-friendly footprint that also suits low-volume production where hand-assembly or socketing is preferred. Operating temperature range is 0°C to 70°C, rated for commercial indoor environments such as bench instrumentation, office equipment, and industrial control panels with climate control. ## 12 µs propagation delay — design for the speed you actually need The 12 µs maximum propagation delay is the headline speed rating. This is not a high-speed comparator for switching power supply feedback loops or data recovery — those applications need sub-microsecond parts. But for thermal shutdown, battery undervoltage lockout, window comparators, or any low-frequency threshold detection, 12 µs is more than adequate and the low power penalty is minimal. Input offset voltage is specified at 10 mV max at 5 V, and the typical CMRR and PSRR are both 80 dB. The integrated reference means the threshold accuracy depends on the internal reference stability, not an external resistor divider — one less tolerance stack to budget. ## Active production, no end-of-life concern ROHS3 compliant. Through-hole DIP packaging means it remains a viable choice for legacy designs, socketed prototypes, and low-volume builds where surface-mount rework is not available.","metaTitle":"MAX933CPA+ Comparator with Voltage Reference","metaDescription":"MAX933CPA+ dual comparator with integrated voltage reference. 50mV hysteresis, 6µA quiescent, 2.5V-11V supply, 8-DIP package.","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":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"80dB CMRR, 80dB PSRR","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C","Current - Output (Typ)":"0.015mA @ 5V","Propagation Delay (Max)":"12µs","Supplier Device Package":"8-PDIP","Current - Quiescent (Max)":"6µA","Voltage - Input Offset (Max)":"10mV @ 5V","Voltage - Supply, Single/Dual (±)":"2.5V ~ 11V, ±1.25V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.08000","currency":"USD"},{"qty":10,"price":"$7.29600","currency":"USD"},{"qty":25,"price":"$6.95680","currency":"USD"},{"qty":100,"price":"$6.04060","currency":"USD"},{"qty":250,"price":"$5.76912","currency":"USD"},{"qty":500,"price":"$5.26008","currency":"USD"},{"qty":1000,"price":"$4.58136","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3ff20f9570cb1853014861278f49fdfd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the typical hysteresis of the MAX933CPA+?","answer":"The MAX933CPA+ has 50 mV of built-in hysteresis per comparator.
