It is not a commercial-grade plastic part — the CDIP tells you this was designed for industrial control, avionics, or long-life equipment where package reliability matters as much as the electrical spec. Four independent amplifiers in one 14-pin package, each capable of 40 mA output drive, with a supply span from 3 V to 32 V. Gain bandwidth product is 1 MHz, input offset voltage typically 2 mV, input bias current 45 nA. Supply current for all four amplifiers is 1.5 mA — useful when the power budget is tight across multiple signal-conditioning channels. ## 3 V to 32 V supply — single-rail or split-rail flexibility The 3 V minimum supply lets this part run from a two-cell battery or a 3.3 V regulated rail; the 32 V maximum covers 24 V industrial buses with margin. No need to split the page into separate single-supply and dual-supply variants — the LM224J handles both. For a ±15 V system the headroom is generous; for a 5 V sensor front-end the quiescent current stays the same 1.5 mA across all four amplifiers. ## Operating temperature: -25°C to 85°C If the board sits in a conditioned indoor cabinet or a vehicle cabin, this is fine. For engine-bay or outdoor pole-mount gear that sees -40°C, you would step to the LM124 or LM224 military-grade sibling in the same CDIP footprint. ROHS3 compliant. This is not a part you need to stockpile against an EOL — it remains in the catalog for new designs and replacement builds alike. ## Date-code and marking — what to check on receipt The 14-CDIP package carries laser-etched marking from TI. The laser etch is a fingerprint — font, depth, and position vary by assembly site and date-code week. A mismatched font or a sanded top surface is the first red flag. Lot traceability through the authorized chain is the cleanest provenance; if the part comes from broker stock, a decap and X-ray check of the die bond pads against the known LinCMOS™ layout is the only way to guarantee it is not a remarked plastic die in a scavenged ceramic package.","metaTitle":"LM224J LinCMOS™ Quad Op-Amp, 1 MHz, 14-CDIP, Active","metaDescription":"Texas Instruments LM224J quad general-purpose op-amp in hermetic 14-CDIP. 1 MHz GBW, 3 V to 32 V supply, -25°C to 85°C.","metaKeywords":null},"attributes":{"series":"LinCMOS™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"LinCMOS™","Package":"Tube","Mounting Type":"Through Hole","Amplifier Type":"General Purpose","Package / Case":"14-CDIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Current - Supply":"1.5mA","Number of Circuits":"4","Current - Input Bias":"45 nA","Operating Temperature":"-25°C ~ 85°C (TJ)","Gain Bandwidth Product":"1 MHz","Voltage - Input Offset":"2 mV","Supplier Device Package":"14-CDIP","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"32 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$16.49000","currency":"USD"},{"qty":10,"price":"$15.15300","currency":"USD"},{"qty":25,"price":"$14.52520","currency":"USD"},{"qty":100,"price":"$12.79780","currency":"USD"},{"qty":250,"price":"$12.16972","currency":"USD"},{"qty":500,"price":"$11.38456","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/760b95161fb34a996ab14789393eeeaa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM224J a quad op amp?","answer":"Yes, the LM224J contains four independent general-purpose op-amp circuits in a single 14-pin CDIP package.
