Product details

AEC-Q100 qualified single op amp for automotive signal chains

Packaged in a SOT-23-5, it fits space-constrained PCB layouts common in engine control units, body controllers, and sensor interface modules.

The 1.8 V minimum supply lets this part run directly from a 1.8 V logic rail or a 3.3 V automotive LDO without a separate op-amp supply. The 5.5 V maximum covers 5 V nominal rails with margin for load-dump transients that stay under the absolute maximum. The 116 µA supply current per amplifier keeps the total current budget low in always-on sensor modules.

Input offset and bias current — signal-path accuracy

Maximum input offset voltage is 1 mV, and input bias current is 14 nA. For a 10 kΩ source impedance, the offset from bias current adds 140 µV, which combined with the 1 mV offset stays under 1.2 mV worst-case. This is adequate for 8-bit to 10-bit accuracy in current-sense or temperature-sense circuits. If sub-millivolt precision is needed, a zero-drift amplifier would be a better fit.

Package and footprint — SOT-23-5 layout notes

The device is supplied in a SOT-23-5 package (SC-74A / SOT-753 equivalent). The 5-pin footprint matches the industry-standard SOT-23-5 land pattern. Surface-mount assembly with standard reflow profiles works; no exposed thermal pad means the power dissipation is limited to the package body. For continuous output currents near 100 mA, keep the ambient below 85°C or add airflow.

Frequently asked questions

Is LMV931MF AEC-Q100 qualified for automotive use?

Yes, the LMV931MF is listed under the Automotive, AEC-Q100 series, confirming qualification for automotive-grade applications including engine control, body electronics, and sensor interfaces.

Can LMV931MF replace LMV321 or other single op amps?

The LMV931MF is a functional equivalent to the LMV321 in the same SOT-23-5 footprint, with the same supply range and similar bandwidth. Pin compatibility should be verified against the specific LMV321 variant's pinout, but the device class and package match.

What is the closest functional second-source for LMV931MF?

The TLV9351IDCKR is a higher-bandwidth alternative (3.5 MHz GBW, 20 V/µs slew rate) in the same SOT-23-5 footprint, but with a 4.5 V minimum supply. For a drop-in replacement at 1.8 V operation, the TLV9351 does not fit; the LMV931MF remains the correct choice for 1.8 V rails.
