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.","metaTitle":"LMV551QDCKRQ1 Automotive Op-Amp, 3 MHz, Rail-to-Rail","metaDescription":"TI LMV551QDCKRQ1 single general-purpose op-amp, AEC-Q100 qualified, 3 MHz GBW, 34 µA supply, rail-to-rail output, -40°C to 125°C, SC-70-5.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"1V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"5-TSSOP, SC-70-5, SOT-353","lifecycle_stage":"eol_hot","Current - Supply":"34µA","Number of Circuits":"1","Current - Input Bias":"20 nA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"3 MHz","Voltage - Input Offset":"1 mV","Supplier Device Package":"SC-70-5","Current - Output / Channel":"25 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.15","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.15000","currency":"USD"},{"qty":10,"price":"$1.02600","currency":"USD"},{"qty":25,"price":"$0.97360","currency":"USD"},{"qty":100,"price":"$0.79970","currency":"USD"},{"qty":250,"price":"$0.74752","currency":"USD"},{"qty":500,"price":"$0.66060","currency":"USD"},{"qty":1000,"price":"$0.52152","currency":"USD"},{"qty":3000,"price":"$0.49200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a1b2b871faee67621b26c1d389f21e22.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the LMV551QDCKRQ1 automotive AEC-Q100 qualified?","answer":"Yes, the LMV551QDCKRQ1 is part of TI's Automotive, AEC-Q100 series, qualified for automotive applications."},{"question":"Does the LMV551QDCKRQ1 have a direct replacement if it becomes obsolete?","answer":"No official replacement is announced.
