Automotive-grade quad op-amp for sensor conditioning and signal chains
The Texas Instruments LMV324Q1MTX/NOPB is a quad-channel general-purpose operational amplifier from the Automotive, AEC-Q100 LMV® series.
What the 1 MHz GBW and 1 V/µs slew rate mean for your signal chain
With a 1 MHz gain-bandwidth product, this op-amp is sized for conditioning signals up to a few tens of kHz with reasonable closed-loop gain — think thermocouple, RTD, or pressure-sensor outputs in an automotive ECU, not video or high-speed ADC drivers. The 1 V/µs slew rate limits full-power bandwidth to roughly 159 kHz at 1 V output swing, so it handles slow-moving sensor waveforms without slew-induced distortion. The 410 µA total supply current for all four channels keeps the thermal budget low in a sealed module.
The AEC-Q100 stamp is the automotive industry's stress-test qualification. It means this part has passed accelerated lifetime testing, high-temperature operating life, and ESD robustness screening specified by the Automotive Electronics Council. For a BOM destined for a Tier-1 supplier's ECU or a body-control module, that qualification is a gate requirement — a commercial LMV324 might work electrically but fails the PPAP paperwork.
Package and footprint — 14-TSSOP
The part comes in a 14-TSSOP body (4.40 mm width, 0.173" pitch), surface-mount only. The fine-pitch leads demand a controlled solder-paste stencil and a reflow profile consistent with the MSL level of this package family — standard JEDEC moisture sensitivity applies. No exposed thermal pad on this package, so dissipation relies on the copper pour and the board's thermal vias.
