Its 16 MHz gain-bandwidth product and 9 V/µs slew rate handle 20 kHz audio bandwidth with margin for active filters. ## AEC-Q100 qualification and temperature grade — the sourcing gate It is rated for deployment in under-hood audio processing modules and cabin-zone amplifiers. Each output can source or sink 50 mA. Housed in a 16-WQFN with exposed pad (4 mm × 4 mm body), the part is surface-mount. The exposed pad ties to the negative supply rail (V−).","metaTitle":"TI OPA1679QRUMRQ1 Audio Op-Amp, 16 MHz, Quad, AEC-Q100","metaDescription":"Texas Instruments OPA1679QRUMRQ1 quad audio op-amp, 16 MHz GBP, 9 V/µs slew rate, rail-to-rail output, AEC-Q100 qualified for -40°C to 125°C operation.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"9V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"20 kHz","Amplifier Type":"Audio","Package / Case":"16-WQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"2mA (x4 Channels)","Number of Circuits":"4","Current - Input Bias":"10 pA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"16 MHz","Voltage - Input Offset":"500 µV","Supplier Device Package":"16-WQFN (4x4)","Current - Output / Channel":"50 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7","priceTiers":[{"qty":1,"price":"$1.70000","currency":"USD"},{"qty":10,"price":"$1.53100","currency":"USD"},{"qty":25,"price":"$1.44440","currency":"USD"},{"qty":100,"price":"$1.23050","currency":"USD"},{"qty":250,"price":"$1.15540","currency":"USD"},{"qty":500,"price":"$1.01098","currency":"USD"},{"qty":1000,"price":"$0.83766","currency":"USD"},{"qty":3000,"price":"$0.81750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b60e0716cec1c864fdbb25a7fb57ef00.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA1679QRUMRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is the OPA1679QRUMRQ1 AEC-Q100 qualified?","answer":"Yes, it is part of the Automotive, AEC-Q100 series, which means it has passed the automotive-grade stress qualification for high-temperature operating life, temperature cycling, and ESD robustness."},{"question":"Can the OPA1679QRUMRQ1 be used as a general-purpose op-amp?","answer":"Yes, while it is optimized for audio applications, its 16 MHz GBP, rail-to-rail output, and wide supply range make it suitable for general-purpose signal conditioning in automotive systems, such as sensor buffering, active filters, and level shifting, as long as the application benefits from the AEC-Q100 qualification."},{"question":"What are alternatives or equivalents to the OPA1679QRUMRQ1?","answer":"The TLV9362IDDFR is a dual-channel general-purpose op-amp with 10.6 MHz GBP and 25 V/µs slew rate, but it lacks the audio-specific optimization and quad-channel count of the OPA1679QRUMRQ1.
