Input bias current is 45 nA typical, and input offset voltage is 2 mV typical — adequate for non-critical DC-coupled stages like level shifting, active filters below 100 kHz, and transducer amplification where precision below 1 mV is not required.","metaTitle":"LM324M LinCMOS Quad Op-Amp, 1 MHz, 14-SOIC, Obsolete","metaDescription":"Texas Instruments LM324M quad general-purpose op-amp, LinCMOS series, 1 MHz GBW, 1.5 mA supply, 3-32 V range, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"LinCMOS™","Package":"Tube","Slew Rate":"-","Output Type":"-","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Not For New Designs","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-SOIC","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"32 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ae8591f33518099ccfd466d961233d87.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM324M/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for the LM324M?","answer":"No official replacement order code is recorded for the LM324M. The LM324 family includes many variants (e.g., LM324N in DIP, LM324DR in SOIC) with similar electrical specs but different package codes. Verify pin-compatibility and temperature grade against your BOM before substituting."},{"question":"What is the difference between the LM324M and the LM324N?","answer":"The LM324M is the surface-mount 14-SOIC variant, while the LM324N is the through-hole 14-DIP variant. Electrical specifications (1 MHz GBW, 1.5 mA supply, 3-32 V range) are identical across the family. The package difference drives the PCB footprint and assembly process."},{"question":"Is the LM324M RoHS compliant?","answer":"The evidence does not specify RoHS compliance status for this order code. Confirm with the supplier at quote time, as obsolete parts may have been manufactured before RoHS transition dates."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM324M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM324M when reusing this data.
