Product details

Automotive-grade single op-amp with 3 MHz GBW at 34 µA

It delivers a 3 MHz gain-bandwidth product while drawing only 34 µA of supply current — a balance that suits battery-monitoring, sensor conditioning, and signal buffering in automotive ECUs where every milliamp is budgeted.

Package and mounting

At 3 MHz unity-gain bandwidth, this part handles sensor outputs up to a few hundred kilohertz with reasonable closed-loop gain — think pressure sensor, temperature, or position-sensor amplification. The 1 V/µs slew rate limits large-signal response at higher gains; for a 2 Vpp output swing the full-power bandwidth sits around 160 kHz. That is adequate for most slow-moving automotive analog signals but not for fast ADC drivers or video lines.

Package and temperature grade for the BOM

Housed in the SC-70-5 (SOT-353) package — five pins, 2.0 mm × 2.1 mm footprint — it fits dense automotive PCBs where board real estate is tight.

Sourcing and lifecycle posture

For dual-sourcing resilience, the TLV9351IDCKR is a functional alternative in the same SC-70-5 footprint — it offers a higher 3.5 MHz GBW and 20 V/µs slew rate but draws 600 µA supply current, so the trade-off is speed versus quiescent power. The LMV551QDCKRQ1 remains the lower-power choice for battery-conscious automotive designs.

Frequently asked questions

Is the LMV551QDCKRQ1 automotive AEC-Q100 qualified?

Yes, the LMV551QDCKRQ1 is part of TI's Automotive, AEC-Q100 series, qualified for automotive applications.

Does the LMV551QDCKRQ1 have a direct replacement if it becomes obsolete?

No official replacement is announced. For a functional alternative in the same SC-70-5 footprint, the TLV9351IDCKR offers higher bandwidth (3.5 MHz) and slew rate (20 V/µs) at the cost of higher supply current (600 µA).
