It lets one channel drive a multiplexed ADC input, a headphone load, or a long cable without an external buffer. The 3 V/µs slew rate keeps distortion low for 1 Vpp signals up to about 100 kHz. ## Package and footprint — 16-WQFN with exposed pad The 16-WFQFN (3x3 mm) with exposed thermal pad requires a solder-paste stencil opening matching the pad dimensions for proper heat transfer. The pad must be connected to a ground plane or the negative supply rail; without the via stitch, continuous output current above 50 mA per channel may push junction temperature beyond the 125°C limit. Surface-mount assembly per standard QFN reflow profiles applies.","metaTitle":"TI OPA4310SIRTER Quad Op-Amp, 3 MHz, 3 V/µs, 1.5-5.5 V","metaDescription":"Texas Instruments OPA4310SIRTER quad general-purpose op-amp: 3 MHz GBW, 3 V/µs slew rate, rail-to-rail output, 110 mA drive per channel, 1.5-5.5 V supply, -40","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":"3V/µs","Output Type":"Push-Pull, Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"16-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"165µA (x4 Channels)","Number of Circuits":"4","Current - Input Bias":"1 pA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"3 MHz","Voltage - Input Offset":"250 µV","Supplier Device Package":"16-WQFN (3x3)","Current - Output / Channel":"110 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"1.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.94","priceTiers":[{"qty":1,"price":"$1.94000","currency":"USD"},{"qty":10,"price":"$1.74400","currency":"USD"},{"qty":25,"price":"$1.64560","currency":"USD"},{"qty":100,"price":"$1.40210","currency":"USD"},{"qty":250,"price":"$1.31652","currency":"USD"},{"qty":500,"price":"$1.15196","currency":"USD"},{"qty":1000,"price":"$0.95448","currency":"USD"},{"qty":2500,"price":"$0.93150","currency":"USD"},{"qty":5000,"price":"$0.93150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a87db704fad7de7dadc6a518ca2c6f6d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA4310SIRTER/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between OPA4310 and OPA4310SIRTER?","answer":"The OPA4310SIRTER suffix denotes the specific package and reel variant: 16-WQFN (3x3 mm) on Tape & Reel.
