At 1 MHz gain-bandwidth, the open-loop gain drops to unity at 1 MHz; for a closed-loop gain of 10, the usable bandwidth is about 100 kHz. That covers audio, low-frequency instrumentation, and control loops, but not video or fast switching. The 1.5 mA total supply current is shared across four amplifiers — roughly 375 µA per channel — making it a reasonable choice for multi-channel designs where power budget matters. ## Hermetic CDIP — why the package matters The 14-CDIP (ceramic dual-in-line) package provides a hermetic seal that resists moisture and outgassing, unlike plastic DIP or SOIC. This makes the LM324J suitable for high-reliability, military, aerospace, and long-life mission equipment where plastic encapsulation is not accepted. Through-hole mounting (0.300\" row spacing) requires no special soldering profile — standard wave or hand solder works. The ceramic body is more brittle than plastic, so mechanical shock and board flex should be managed. The LM324J operates from a single supply of 3 V to 32 V (or dual supplies up to ±16 V), covering common 5 V, 12 V, and 24 V industrial rails. For dual-sourcing or a plastic-package alternative, the LM324N (same electrical in PDIP) is a common cross-shop candidate, but the LM324J is the only hermetic CDIP variant in the family.","metaTitle":"LM324J Quad General-Purpose Op-Amp, 1 MHz, 14-CDIP","metaDescription":"Texas Instruments LM324J quad general-purpose op-amp in hermetic 14-CDIP. 1 MHz GBW, 1.5 mA supply, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"LinCMOS™","Package":"Tube","Slew Rate":"-","Output Type":"-","Mounting Type":"Through Hole","Amplifier Type":"General Purpose","Package / Case":"14-CDIP (0.300\\\", 7.62mm)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"1.5mA","Number of Circuits":"4","Base Product Number":"LM324","Current - Input Bias":"45 nA","Operating Temperature":"0°C~70°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":"$16.8800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/760b95161fb34a996ab14789393eeeaa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM324J/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between LM324J and LM324N?","answer":"The LM324J is the hermetic ceramic DIP (14-CDIP) version, while the LM324N is the plastic PDIP version.
