The slew rate limits full-power bandwidth to roughly 5 kHz at 5 V output swing, so do not expect it to reproduce 20 kHz audio at full amplitude. The rail-to-rail output stage lets the OPA347UA swing within millivolts of either supply rail, which is the difference between a 3.0 V ADC reading 90% of full scale versus 98% when the op-amp is the last gain stage. Supply range spans 2.3 V (two alkaline cells nearly depleted) to 5.5 V (the USB VBUS upper limit), so the same BOM line works across battery portable and 5 V industrial designs. The 2 mV input offset voltage is the max across the full temperature range, not a typical at 25°C, so the error budget stays valid at the hot end.","metaTitle":"TI OPA347UA General Purpose Op-Amp, 350 kHz, 8-SOIC","metaDescription":"Texas Instruments OPA347UA general purpose op-amp: 350 kHz GBW, 0.17 V/µs slew rate, rail-to-rail output, 20 µA supply, -55°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Slew Rate":"0.17V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"20µA","Number of Circuits":"1","Current - Input Bias":"0.5 pA","Operating Temperature":"-55°C ~ 125°C","Gain Bandwidth Product":"350 kHz","Voltage - Input Offset":"2 mV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"17 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.95","priceTiers":[{"qty":1,"price":"$0.95000","currency":"USD"},{"qty":10,"price":"$0.84700","currency":"USD"},{"qty":25,"price":"$0.80440","currency":"USD"},{"qty":100,"price":"$0.66070","currency":"USD"},{"qty":250,"price":"$0.61760","currency":"USD"},{"qty":500,"price":"$0.54580","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/137082ea94866aaff629a992f3044a9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA347UA/alternatives.json"},"ai":{"faq":[{"question":"What is an equivalent or second-source for OPA347UA?","answer":"The OPA4374AIPWT is a quad-channel CMOS op-amp with similar 0.5 pA input bias current and rail-to-rail output, but it operates from 2.7 V minimum supply and offers 6.5 MHz gain-bandwidth at 600 µA per channel. It is not a pin-compatible drop-in — the OPA4374 is a quad in a TSSOP-14 package — but it shares the same design philosophy for low-power precision sensing."},{"question":"Is the OPA347UA rail-to-rail?","answer":"Yes, the output stage is rail-to-rail. The input common-mode range is not rail-to-rail — it extends from the negative supply to within approximately 1 V of the positive rail, so high-side sensing at 3.3 V single supply requires a different part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA347UA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA347UA when reusing this data.
