Each channel draws just 20 µA of supply current, making the whole quad consume 80 µA — a fit for battery-powered instrumentation, portable medical devices, and sensor conditioning where every microamp counts. The 350 kHz gain-bandwidth product and 0.17 V/µs slew rate place it in the low-frequency signal-conditioning class — think thermocouple amplifiers, photodiode front-ends, and active filters below 50 kHz. ## What the key ratings mean for your circuit Rail-to-rail output swing means the output can reach within millivolts of both supply rails — useful when running from a 3.3 V or 5 V single supply and you need the full dynamic range into an ADC. Input bias current of 0.5 pA typ is low enough that a 10 MΩ source resistor causes only 5 µV of offset error — negligible for most precision sensor interfaces, though the 2 mV input offset voltage (Vos) is the dominant DC error term to budget. Operating temperature from -55°C to 125°C covers the full industrial and military-temperature range — the same quad can serve an engine-bay sensor module and a lab data logger without a grade change. Supply span from 2.3 V to 5.5 V means it runs directly from a single Li-Ion cell (3.0-4.2 V) or a regulated 3.3 V / 5 V rail — no extra LDO needed for the op-amp supply. Each output can source or sink 17 mA — enough to drive a reference input of a successive-approximation ADC or a small headphone load, but not a speaker or relay coil. ## Package and assembly fit The 14-TSSOP package (4.40 mm body width, 0.65 mm pin pitch) is hand-solderable with a fine-tip iron and magnification — no hot-air or reflow required for prototypes. Surface-mount mounting is standard; the 0.65 mm pitch is forgiving enough for a two-layer PCB with proper pad geometry.","metaTitle":"TI OPA4347EA/250 Quad Op-Amp, 350 kHz, 14-TSSOP","metaDescription":"Texas Instruments OPA4347EA/250 quad general-purpose op-amp, 350 kHz GBW, 0.17 V/µs slew rate, rail-to-rail output, 20 µA supply per channel, 14-TSSOP.","metaKeywords":null},"attributes":{"series":"microPOWER™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"microPOWER™","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"0.17V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"20µA (x4 Channels)","Number of Circuits":"4","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":"14-TSSOP","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":"$4.24","priceTiers":[{"qty":1,"price":"$4.24000","currency":"USD"},{"qty":10,"price":"$3.80700","currency":"USD"},{"qty":25,"price":"$3.59880","currency":"USD"},{"qty":100,"price":"$3.11910","currency":"USD"},{"qty":250,"price":"$2.95916","currency":"USD"},{"qty":500,"price":"$2.65524","currency":"USD"},{"qty":1250,"price":"$2.26350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/137082ea94866aaff629a992f3044a9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA4347EA%2F250/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the OPA4347EA/250 and how is it quoted?","answer":"The OPA4347EA/250 is sourced through authorized and independent distribution."},{"question":"Can I hand-solder the OPA4347EA/250?","answer":"Yes, the 14-TSSOP package with 0.65 mm pin pitch is hand-solderable with a fine-tip iron and magnification — no reflow oven required for prototypes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA4347EA-250","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA4347EA-250 when reusing this data.
