Supply voltage can range from 9 V to 36 V, supporting both single-supply and split-rail configurations common in industrial control and test equipment. With a 4 MHz gain-bandwidth product, the OPA131U can close a gain-of-10 amplifier with a -3 dB bandwidth around 400 kHz, adequate for many sensor conditioning and audio line-level paths. For a 5 V peak-to-peak output, the full-power bandwidth is roughly 300 kHz — enough for fast ADC driver stages or PWM reconstruction filters. In precision DC measurement circuits, you may need to account for this offset in software calibration or select a lower-offset part if sub-100 µV accuracy is required. The 5 pA bias current is low enough that 10 MΩ source resistors introduce only 50 µV of additional offset error — negligible in most designs. This wide range makes it drop-in compatible with legacy ±15 V industrial rails as well as modern 12 V or 24 V single-supply systems.","metaTitle":"OPA131U General-Purpose Op-Amp, 4 MHz GBW, 10 V/µs, 8-SOIC","metaDescription":"Texas Instruments OPA131U general-purpose op-amp: 4 MHz GBW, 10 V/µs slew rate, 200 µV offset, 5 pA bias. 8-SOIC, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Slew Rate":"10V/µs","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.5mA","Number of Circuits":"1","Current - Input Bias":"5 pA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"4 MHz","Voltage - Input Offset":"200 µV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"25 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"9 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.5","priceTiers":[{"qty":1,"price":"$6.50000","currency":"USD"},{"qty":10,"price":"$5.83500","currency":"USD"},{"qty":25,"price":"$5.51640","currency":"USD"},{"qty":100,"price":"$4.78100","currency":"USD"},{"qty":250,"price":"$4.53580","currency":"USD"},{"qty":500,"price":"$4.06996","currency":"USD"},{"qty":1000,"price":"$3.46950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/660f7d73595f719b25d0cb9cbe0a37b0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA131U/alternatives.json"},"ai":{"faq":[{"question":"Is the OPA131U obsolete?","answer":"There is no indication of discontinuation or last-time-buy."},{"question":"What are the alternatives to OPA131U?","answer":"The TLV9351 is a more modern CMOS design with lower offset (350 µV) and higher output current (60 mA), but it operates from a single 4.5 V supply only, unlike the OPA131U's 9 V to 36 V range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA131U","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA131U when reusing this data.
