The gain-bandwidth product is 100 kHz with a slew rate of 0.05 V/µs — this is a low-frequency part, suited for DC signal conditioning, sensor buffers, and audio-band filtering, not for high-speed ADC drivers or fast control loops. ## Supply range and single-supply capability The LP324M operates from a single supply spanning 3 V to 32 V, or a split supply of ±1.5 V to ±16 V. That covers common rails from 3.3 V logic to 24 V industrial buses. The input common-mode range includes ground in single-supply mode, so it can sense signals near the negative rail — useful for low-side current sensing or ground-referenced inputs. ## Temperature grade and environment It is not specified for automotive under-hood or industrial extended-temperature applications. ## Input offset and bias current — what they mean Input offset voltage is 2 mV typical, and input bias current is 2 nA typical. For a general-purpose op-amp these are adequate for many sensor and signal-conditioning tasks, but precision DC applications (e.g., microvolt-level measurements) would want a lower-offset amplifier. ## Lifecycle and sourcing It is RoHS non-compliant (lead-bearing), so check your assembly line's exemption status if you are shipping to RoHS-regulated markets.","metaTitle":"LP324M Quad General-Purpose Op-Amp, 100 kHz, 14-SOIC","metaDescription":"LP324M quad op-amp by Texas Instruments: 100 kHz GBP, 85 µA supply, 3 V to 32 V single supply, 14-SOIC.

The LP324M draws 85 µA per amplifier versus roughly 500 µA for the LM324, at the cost of a lower gain-bandwidth product (100 kHz vs 1 MHz) and slower slew rate (0.05 V/µs vs 0.5 V/µs). Pin-compatible in the same 14-SOIC footprint."},{"question":"Can LP324M be used as a comparator?","answer":"Technically yes, but it is not recommended. The 0.05 V/µs slew rate means very slow output transitions, and the lack of internal hysteresis can cause oscillation near the switching threshold. A dedicated comparator like the TLV3501 would be a better choice for fast or clean switching."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP324M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP324M when reusing this data.
