The 31 MHz gain-bandwidth product and 56 MHz -3 dB bandwidth back it up for small-signal paths, but the slew rate is what buys you large-signal bandwidth without burning the power budget. Rail-to-rail output swing means you get the full supply range into an ADC or comparator input without an extra rail splitter. ## Supply current vs. slew rate — the BOM trade-off At 250 µA supply current, the OPA835IRUNT sits in a sweet spot between micropower op-amps (sub-100 µA) that slew at a few V/µs and high-speed parts (several mA) that hit 1000 V/µs. If your signal chain needs to settle a 10 V step in under 40 ns, this part does it without forcing a regulator upgrade for the op-amp rail. The 100 µV input offset voltage and 200 nA input bias current are typical for a bipolar-input voltage-feedback amp at this speed — adequate for 12-bit systems, but watch the offset drift if you are DC-coupling a precision sensor. Without that, the junction-to-ambient thermal resistance rises and the part will thermally cycle at high ambient temperatures.","metaTitle":"TI OPA835IRUNT Voltage Feedback Op-Amp, 56 MHz, 260 V/µs","metaDescription":"Texas Instruments OPA835IRUNT voltage-feedback op-amp: 56 MHz -3 dB BW, 260 V/µs slew rate, rail-to-rail output, 250 µA supply. 10-WQFN (2x2 mm). -40 to 125°C.","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":"260V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"56 MHz","Amplifier Type":"Voltage Feedback","Package / Case":"10-WFQFN","lifecycle_stage":"eol_hot","Current - Supply":"250µA","Number of Circuits":"1","Current - Input Bias":"200 nA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"31 MHz","Voltage - Input Offset":"100 µV","Supplier Device Package":"10-WQFN (2x2)","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.85","priceTiers":[{"qty":1,"price":"$2.85000","currency":"USD"},{"qty":10,"price":"$2.55600","currency":"USD"},{"qty":25,"price":"$2.41600","currency":"USD"},{"qty":100,"price":"$2.09390","currency":"USD"},{"qty":250,"price":"$1.98648","currency":"USD"},{"qty":500,"price":"$1.78248","currency":"USD"},{"qty":1250,"price":"$1.51950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b2ce5b50a8eea67d8b5671b88c3e818c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA835IRUNT/alternatives.json"},"ai":{"faq":[{"question":"What is an equivalent or replacement for OPA835IRUNT?","answer":"The TLV9351IDCKR is a general-purpose alternative but its 20 V/µs slew rate and higher supply current make it unsuitable for high-speed signal chains where the OPA835IRUNT's slew rate is needed.
