At 4.5 V the current drops proportionally, but the headline 140 µA is the worst-case number to budget for the rail. The 5 pA input bias current means the OPA191IDGKT can interface directly with high-impedance sources like pH probes or photodiode transimpedance stages without an external buffer — the bias error stays negligible.","metaTitle":"TI OPA191IDGKT General-Purpose Op-Amp, 5 µV Offset, 8-VSSOP","metaDescription":"Texas Instruments OPA191IDGKT single general-purpose op-amp: 5 µV input offset, 2.5 MHz GBW, 5.5 V/µs slew rate, rail-to-rail output, 4.5–36 V supply, -40 to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"5.5V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"140µA","Number of Circuits":"1","Current - Input Bias":"5 pA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"2.5 MHz","Voltage - Input Offset":"5 µV","Supplier Device Package":"8-VSSOP","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.67","priceTiers":[{"qty":1,"price":"$3.67000","currency":"USD"},{"qty":10,"price":"$3.29700","currency":"USD"},{"qty":25,"price":"$3.11720","currency":"USD"},{"qty":100,"price":"$2.70160","currency":"USD"},{"qty":250,"price":"$2.56304","currency":"USD"},{"qty":500,"price":"$2.29980","currency":"USD"},{"qty":1250,"price":"$1.96050","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/40bff4decb183d6d8aea0f8f4662bc51.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA191IDGKT/alternatives.json"},"ai":{"faq":[{"question":"What is the gain bandwidth product of OPA191IDGKT?","answer":"The gain-bandwidth product is 2.5 MHz, with a slew rate of 5.5 V/µs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA191IDGKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA191IDGKT when reusing this data.
