This makes the TL084QD a practical choice for multi-channel signal conditioning in battery-powered or thermally constrained automotive modules, where every milliamp matters. The input bias current is 30 pA typical, a direct benefit of the JFET input stage. This allows the op-amp to interface directly with high-impedance sensors (e.g., piezoelectric, photodiode) without significant DC error from bias current. This qualifies it for under-hood, engine bay, and chassis-domain electronics where the ambient temperature can exceed 105°C. The supply voltage span of 10 V to 30 V gives headroom for unregulated automotive rails (e.g., 12 V battery with load-dump transients), though the absolute maximum rating should be checked against the system's worst-case transient. The 1.27 mm pin pitch is layout-friendly for two-layer automotive PCBs, and the SOIC footprint is widely supported across assembly houses.","metaTitle":"TL084QD Quad JFET Op-Amp, Automotive AEC-Q100, 3 MHz","metaDescription":"TL084QD quad JFET op-amp from Texas Instruments, AEC-Q100 qualified, 3 MHz GBW, 13 V/µs slew rate, 1.4 mA supply, -40°C to 125°C, 14-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tube","Slew Rate":"13V/µs","Output Type":"-","Mounting Type":"Surface Mount","Amplifier Type":"J-FET","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"1.4mA (x4 Channels)","Number of Circuits":"4","Base Product Number":"TL084","Current - Input Bias":"30 pA","Operating Temperature":"-40°C~125°C","Gain Bandwidth Product":"3 MHz","Voltage - Input Offset":"3 mV","Supplier Device Package":"14-SOIC","Current - Output / Channel":"10 mA","Voltage - Supply Span (Max)":"30 V","Voltage - Supply Span (Min)":"10 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd0d2120e3c12ca626ffeb622ac6a207.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL084QD/alternatives.json"},"ai":{"faq":[{"question":"What is the TL084QD slew rate?","answer":"The TL084QD has a slew rate of 13 V/µs typical.
