The 25 µV input offset voltage and 2 nA input bias current set the floor for DC measurement error — in a bridge application with a 10 mV full-scale output, the offset contributes 0.25% error before any gain is applied. The 1.3 MHz bandwidth supports gains up to 1000× without excessive noise bandwidth; beyond that, the gain-bandwidth product limits the usable frequency range. The 4V/µs slew rate ensures the output can swing rail-to-rail on a 10 V step in about 2.5 µs, adequate for multiplexed data-acquisition systems scanning at tens of kilohertz. The INA128UA/2K5 operates from a single supply as low as 4.5 V up to 36 V, covering both 5 V and ±15 V industrial rails.","metaTitle":"INA128UA/2K5 Instrumentation Amplifier, 1.3 MHz","metaDescription":"Texas Instruments INA128UA/2K5 precision instrumentation amplifier: 25 µV offset, 2 nA bias, 1.3 MHz bandwidth, 4V/µs slew rate.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"4V/µs","Output Type":"-","Mounting Type":"Surface Mount","-3db Bandwidth":"1.3 MHz","Amplifier Type":"Instrumentation","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"700µA","Number of Circuits":"1","Base Product Number":"INA128","Current - Input Bias":"2 nA","Operating Temperature":"-40°C~125°C","Voltage - Input Offset":"25 µV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"15 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.3600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38ef53acfab362c1f4307adc148d9e91.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA128UA%2F2K5/alternatives.json"},"ai":{"faq":[{"question":"How does INA128UA/2K5 compare to the AD620?","answer":"Both are classic three-op-amp instrumentation amplifiers in 8-SOIC. The INA128 offers a lower input offset voltage (25 µV typ vs 50 µV typ for the AD620) and a wider supply range (36 V vs 30 V), but the AD620 draws slightly lower quiescent current (900 µA typ vs 700 µA for the INA128). Pin-compatible in the same footprint, so a board designed for one can typically accept the other with a BOM swap."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA128UA-2K5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA128UA-2K5 when reusing this data.
