It integrates four independent op-amp channels into one through-hole package, each rated for 40 mA output drive and drawing 1.5 mA total supply current. With a 1 MHz gain-bandwidth product and 3 V to 32 V supply range, this part covers the standard signal-conditioning sweet spot — sensor buffering, active filters below 100 kHz, and DC-level shifting in commercial-temperature equipment. The 1 MHz gain-bandwidth product sets a practical closed-loop bandwidth of 100 kHz at a gain of 10. Above that, phase margin erodes and the part cannot maintain linear operation. For audio-band filtering below 20 kHz or DC instrumentation loops, this is ample; for video or high-speed ADC drive, it is not. Input offset voltage is 2 mV typical, input bias current 45 nA — adequate for single-supply 5 V or 12 V circuits where the signal is several hundred millivolts or more. For microvolt-level precision, a zero-drift amplifier would be the better call. Texas Instruments no longer manufactures this specific variant. Available inventory is limited to surplus and broker-channel stock. The 14-PDIP package and through-hole format mean this part is most often sought for repair, legacy board support, or one-off builds where a drop-in replacement is required.","metaTitle":"LM324AN/PB LinCMOS Quad Op-Amp, 1 MHz, Obsolete","metaDescription":"TI LM324AN/PB general-purpose quad op-amp, 1 MHz gain-bandwidth, 14-PDIP, 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™","Packaging":"Tube","Slew Rate":"-","Output Type":"-","Part Status":"Obsolete","Mounting Type":"Through Hole","Amplifier Type":"General Purpose","Package / Case":"14-DIP (0.300\\\", 7.62mm)","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-PDIP","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"32 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1a86f1e7e8c6983c08ab9f7c4acb68a9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM324AN%2FPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM324AN/PB obsolete?","answer":"Yes, the LM324AN/PB is listed as Obsolete.
