LMV324MT/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LMV324MT/NOPB is a quad low-voltage operational amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device features rail-to-rail output swing, achieving performance within 10 mV of the positive rail and 65 mV of the negative rail at a 10 kΩ load. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 1 V/µs, and a typical supply current of 410 µA for all four amplifiers. The input common-mode voltage range includes ground, extending down to -0.2 V.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix 'NOPB' confirms lead-free status and RoHS compliance as specified by Texas Instruments. Confirm the package designation matches the TSSOP-14 form factor required for your PCB layout. Ensure the component grade aligns with your industrial temperature requirements of -40°C to +125°C before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when space efficiency and low voltage operation are critical design constraints. It serves as a low-voltage alternative to the standard LM324, offering improved speed-to-power ratios. Consider its rail-to-rail output and ground-referenced inputs if single-supply operation near zero volts is necessary for your signal chain.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMV3xx-N family, which includes single (LMV321), dual (LMV358), and quad (LMV324) variants. These amplifiers utilize an advanced submicron silicon-gate BiCMOS process to provide bipolar input and output stages. This architecture delivers improved noise performance and higher output current drive compared to standard CMOS counterparts.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The LMV324-N is the direct functional equivalent within the same series. For legacy designs requiring higher voltage tolerance up to 30 V, the LM324 is the traditional predecessor, though it lacks rail-to-rail output and exhibits crossover distortion.
