Each channel draws 6 mA supply current, so the total quiescent is 12 mA — moderate for this speed class, but worth budgeting in a multi-rail system. The 100V/µs slew rate means this op-amp can swing a 5 V peak-to-peak output in 50 ns, which is fast enough to preserve the edges on a 10 MHz square wave or drive the input of a high-speed ADC without excessive slew-induced distortion. The 75 MHz -3dB bandwidth (gain-bandwidth product is 68 MHz) tells you the small-signal gain holds up well into the tens of megahertz. If you are conditioning signals from a fast photodiode or a magnetic pickup, this part keeps the phase shift manageable. The 90 mA output current per channel gives it enough drive to handle a 50 Ω back-terminated cable or a modest capacitive load without an external buffer. ## RoHS flag — check your compliance path If your BOM needs a lead-free assembly process, you will need to either qualify an exemption or look at a RoHS-compliant alternate. ## Package and footprint — what fits on the board No exposed pad, which simplifies layout but means the thermal path is through the leads — keep the ambient below 85°C for sustained high-output current. The shipping form is Bulk, not tape-and-reel, so plan for manual placement or a tube feeder if you are running a pick-and-place line.","metaTitle":"OPA2631U/2K5 Voltage Feedback Op-Amp, 100V/µs Slew Rate","metaDescription":"TI OPA2631U/2K5 dual voltage feedback op-amp, 75 MHz -3dB bandwidth, 100V/µs slew rate, 2.7-10.5V supply, industrial temp.","metaKeywords":null},"attributes":{"series":"SpeedPlus™","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"SpeedPlus™","Package":"Bulk","Slew Rate":"100V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"75 MHz","Amplifier Type":"Voltage Feedback","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"6mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"11 µA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"68 MHz","Voltage - Input Offset":"2.5 mV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"90 mA","Voltage - Supply Span (Max)":"10.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.35","priceTiers":[{"qty":222,"price":"$1.35000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA2631U%2F2K5/alternatives.json"},"ai":{"faq":[{"question":"Is OPA2631U/2K5 RoHS compliant?","answer":"No — it is listed as RoHS non-compliant.
