Input common-mode range is not rail-to-rail on this family — the datasheet typical input range goes to about 1.5 V below the positive rail at 5 V supply, so high-side current sensing at 3.3 V single supply needs a different part. The 1 pA input bias current lets you interface directly to high-impedance sources like pH probes or photodiode amplifiers without an external JFET buffer. Supply range runs from 4 V to 12 V, which covers most 5 V and 12 V industrial rails but not 3.3 V systems. ## Package and temperature — field-swap reality Marking is typically a three-character code on the package body; orientation is standard with pin 1 at the top-left when the marking is read upright, so you can get it right without a magnifier on a good day.","metaTitle":"TI OPA703NA/3K General Purpose Op-Amp, 1 MHz GBW, SOT-23-5","metaDescription":"Texas Instruments OPA703NA/3K single general-purpose op-amp with 1 MHz GBW, 0.6 V/µs slew rate, rail-to-rail output, 160 µA supply, SOT-23-5.","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":"0.6V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Current - Supply":"160µA","Number of Circuits":"1","Current - Input Bias":"1 pA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"1 MHz","Voltage - Input Offset":"160 µV","Supplier Device Package":"SOT-23-5","Current - Output / Channel":"10 mA","Voltage - Supply Span (Max)":"12 V","Voltage - Supply Span (Min)":"4 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.97","priceTiers":[{"qty":1,"price":"$3.97000","currency":"USD"},{"qty":10,"price":"$3.56200","currency":"USD"},{"qty":25,"price":"$3.36760","currency":"USD"},{"qty":100,"price":"$2.91860","currency":"USD"},{"qty":250,"price":"$2.76892","currency":"USD"},{"qty":500,"price":"$2.48456","currency":"USD"},{"qty":1000,"price":"$2.11800","currency":"USD"},{"qty":3000,"price":"$2.11800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1098e410157d907d6f59e9c570b8164e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA703NA%2F3K/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to OPA703NA/3K?","answer":"It fits the same SOT-23-5 footprint and rail-to-rail output."},{"question":"Is OPA703NA/3K single or dual channel?","answer":"It is a single-channel op-amp — one amplifier in the SOT-23-5 package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA703NA-3K","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA703NA-3K when reusing this data.
