Technical 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.

That is adequate for most slow-moving automotive analog signals but not for fast ADC drivers or video lines.

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.

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.
