The supply range spans 3 V to 30 V single supply or ±1.5 V to ±15 V dual supplies, making it a drop-in for 5 V, 12 V, and 24 V board-level signal conditioning — sensor buffers, active filters, comparator functions, and DC gain stages where speed is secondary to flexibility. The 1.2 MHz gain-bandwidth product sets the usable closed-loop gain bandwidth: at a gain of 10, expect a -3 dB point around 120 kHz. That is fine for DC measurement, audio-frequency filtering, and slow control loops, but it will round off fast edges in pulse-width modulation or high-speed comparator applications. For a 20 nA input bias current and 3 mV typical input offset, the DC precision is adequate for general-purpose work but not precision instrumentation. ## Supply rails and output drive The 3 V minimum supply lets it run from a single lithium cell or a 3.3 V rail; the 30 V maximum covers 24 V industrial buses with margin. Total quiescent current for all four amplifiers is 1.4 mA typical — about 350 µA per channel — which keeps the power budget modest in multi-channel designs. The 14-SOIC (5.30 mm body width) is a standard footprint with 1.27 mm pitch. It reflows cleanly with a typical lead-free profile and is easy to hand-solder or hot-air rework.","metaTitle":"LM324NSR Quad General Purpose Op-Amp, 1.2 MHz, 14-SOIC","metaDescription":"TI LM324NSR quad general-purpose op-amp in 14-SOIC. 1.2 MHz GBW, 0.5 V/µs slew rate, 3 V to 30 V supply.

Electrically they are the same quad op-amp with identical 1.2 MHz GBW, 0.5 V/µs slew rate, and 3 V to 30 V supply range. The choice is purely a board-assembly decision — reflow versus wave-solder or socket."},{"question":"What can I use instead of LM324NSR?","answer":"The LM324NSR is a standard quad general-purpose op-amp in 14-SOIC. Many manufacturers offer pin-compatible equivalents — the LM324 series is a widely second-sourced industry standard. For a higher-speed alternative with rail-to-rail output, consider the TLV9351IDCKR (single, 3.5 MHz, 20 V/µs) or TLV9362IDDFR (dual, 10.6 MHz, 25 V/µs), though these are not quad and have different pinouts."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM324NSR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM324NSR when reusing this data.
