Rail-to-rail output swing lets it drive ADC inputs or signal lines directly from a 2.3 V minimum supply up to 5.5 V maximum, covering single Li-ion through 5 V regulated rails. The 0.5 pA input bias current suits high-impedance sensor interfaces — photodiode amplifiers, pH probes, or piezoelectric sensors — where bias current error would otherwise swamp the signal. Output drive is rated 17 mA per channel, enough to swing a 10 kΩ load rail-to-rail at 5 V. Most op-amps in the 20 µA supply class top out at 85°C or 105°C. The 2 mV input offset voltage is typical for this class — not a precision instrumentation amp, but adequate for general-purpose signal conditioning in harsh environments. ## Dual-channel in SOIC-8 — board-area efficiency Two amplifiers in a single 8-pin SOIC (3.90 mm body width) saves board area versus two SOT-23 or SC-70 single-channel parts. No exposed thermal pad — the 17 mA output per channel keeps self-heating low enough that the standard SOIC-8 package handles dissipation without special layout treatment.","metaTitle":"TI OPA2347UA Dual Op-Amp, 350 kHz, 0.17 V/µs, microPOWER","metaDescription":"Texas Instruments OPA2347UA dual general-purpose op-amp in SOIC-8.","metaKeywords":null},"attributes":{"series":"microPOWER™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"microPOWER™","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 (x2 Channels)","Number of Circuits":"2","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":"$1.7","priceTiers":[{"qty":1,"price":"$1.70000","currency":"USD"},{"qty":10,"price":"$1.52000","currency":"USD"},{"qty":25,"price":"$1.44240","currency":"USD"},{"qty":100,"price":"$1.18490","currency":"USD"},{"qty":250,"price":"$1.10760","currency":"USD"},{"qty":500,"price":"$0.97880","currency":"USD"},{"qty":1000,"price":"$0.77274","currency":"USD"},{"qty":2500,"price":"$0.72900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/137082ea94866aaff629a992f3044a9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA2347UA/alternatives.json"},"ai":{"faq":[{"question":"What package does OPA2347UA come in?","answer":"The supplier device package is 8-SOIC."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA2347UA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA2347UA when reusing this data.
