The supply span from 3 V to 32 V covers single 5 V logic rails, 12 V industrial buses, and 24 V battery systems without needing a secondary regulator. With a slew rate of 0.05 V/µs and gain-bandwidth product of 100 kHz, this part is squarely in the micropower, low-frequency class. For a 1 V peak output swing, the maximum undistorted frequency is roughly 8 kHz — fine for DC sensor outputs or low-speed telemetry, but not for audio line-level signals or switching amplifier loops. The 2 mV input offset voltage and 2 nA input bias current are adequate for general-purpose conditioning of millivolt-level signals from resistive bridges or thermocouples, though a precision amplifier would be needed for microvolt-level measurements. The 3 V minimum supply lets this quad op-amp run directly from a single lithium cell or a 3.3 V regulated rail, while the 32 V maximum allows operation on 24 V industrial supplies with headroom. The 14-TSSOP package keeps the board footprint small for multi-channel designs, and the surface-mount mounting suits automated assembly. ## Lifecycle and sourcing posture It is ROHS3 compliant. There is no official TI successor listed for this exact order code, but the LP324 family is broadly second-sourced by multiple manufacturers — the standard LM324 pinout is compatible, though the LP324's micropower supply current (85 µA versus roughly 500 µA for the LM324) is the key differentiator.","metaTitle":"Texas Instruments LP324MT/NOPB Quad Op-Amp, 100 kHz","metaDescription":"Texas Instruments LP324MT/NOPB quad general-purpose op-amp in 14-TSSOP. 100 kHz GBW, 0.05 V/µs slew rate, 85 µA supply, 3 V to 32 V range.

The LP324 family is broadly pin-compatible with the industry-standard LM324 quad op-amp, but the LP324 draws significantly less supply current (85 µA per package versus roughly 500 µA for the LM324). Evaluate the parametric differences against your signal bandwidth and power budget before substituting."},{"question":"Can LP324MT/NOPB operate on a single 5V supply?","answer":"Yes. The supply voltage range spans 3 V to 32 V, so a single 5 V rail is well within the operating range."},{"question":"How does LP324MT/NOPB compare to the standard LM324?","answer":"The LP324 is the micropower variant of the classic LM324 quad op-amp. The key difference is supply current: the LP324 draws 85 µA for all four amplifiers, while a typical LM324 draws around 500 µA. The LP324 trades speed for that power savings — its 100 kHz GBW and 0.05 V/µs slew rate are lower than the LM324's typical 1 MHz GBW and 0.5 V/µs slew rate. Both share the same pinout and operate from 3 V to 32 V supplies. Choose the LP324 when every microamp of quiescent current matters and signal frequencies stay below a few kilohertz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP324MT-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP324MT-NOPB when reusing this data.
