That flexibility, combined with the 1.4 mA total quiescent current across all four amplifiers, makes it a workhorse for multi-channel boards where per-channel power budget matters. ## Supply range and current — the BOM-fit numbers The 3 V minimum supply span lets this part operate from a single lithium cell or a 3.3 V rail, while the 30 V maximum covers 24 V industrial buses with headroom for transients. The 1.4 mA supply current for all four channels works out to 350 µA per amplifier — low enough that a 24 V, 100 mA supply can feed dozens of these on a backplane without thermal issues. The 20 nA input bias current and 3 mV input offset voltage are typical for this class; they set the floor for DC accuracy in precision applications like strain-gauge bridges. ## 14-DIP package — rework and layout realities The 14-DIP (0.300-inch width, 7.62 mm) through-hole package is the most technician-friendly option in the LM324 family. The 0.100-inch pin pitch matches standard prototyping breadboards and perfboards, so this is the variant to pick for a proof-of-concept or a low-volume production run where hand-assembly is the plan. Through-hole means the part survives multiple rework cycles — desolder with a vacuum tool or solder wick, reinsert, reflow. No moisture sensitivity level to track; no bake-out required before soldering. This is a low-risk BOM line for new designs as well as legacy support.","metaTitle":"LM324KN General Purpose Op-Amp, 1.2 MHz GBWP, 14-DIP","metaDescription":"Texas Instruments LM324KN quad general-purpose op-amp, 1.2 MHz gain bandwidth, 0.5 V/µs slew rate, 3 V to 30 V supply, 14-DIP through-hole package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Slew Rate":"0.5V/µs","Output Type":"-","Mounting Type":"Through Hole","Amplifier Type":"General Purpose","Package / Case":"14-DIP (0.300\\\", 7.62mm)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"1.4mA (x4 Channels)","Number of Circuits":"4","Base Product Number":"LM324","Current - Input Bias":"20 nA","Operating Temperature":"0°C~70°C(TA)","Gain Bandwidth Product":"1.2 MHz","Voltage - Input Offset":"3 mV","Supplier Device Package":"14-PDIP","Current - Output / Channel":"30 mA","Voltage - Supply Span (Max)":"30 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/82fa63e30c4c5cc784748c213bc64c16.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM324KN/alternatives.json"},"ai":{"faq":[{"question":"Is LM324KN the same as LM324N?","answer":"The LM324KN and LM324N are functionally identical — same quad general-purpose op-amp core, same 1.2 MHz GBWP, same 3 V to 30 V supply range, same 14-DIP package.
