It delivers a 9.2 MHz gain-bandwidth product with a 15 V/µs slew rate, enough to handle full audio bandwidth with margin for anti-aliasing filtering ahead of a sigma-delta ADC. The differential output eliminates the need for a separate balun or transformer when driving the differential input of a codec or audio ADC — a common topology in professional audio gear, active speakers, and automotive infotainment head units. ## Supply range and output drive Supply span runs from 3 V to 36 V. Each output channel can source or sink 31 mA. ## DC precision and temperature range Input offset voltage is 20 µV typical. Input bias current is 200 pA. ## Package and sourcing note The 8-VSSOP footprint is 3.00 mm wide, a common land pattern for audio signal-chain designs. The part is available in Tape & Reel or Cut Tape for prototype and production volumes. Lifecycle status is Active, so no near-term last-time-buy risk for new designs.","metaTitle":"TI OPA1637DGKT Audio Op Amp, Differential Output, 8-VSSOP","metaDescription":"TI OPA1637DGKT audio differential op amp: 9.2 MHz GBP, 15 V/µs slew rate, 3-36 V supply, 20 µV offset, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"15V/µs","Output Type":"Differential","Mounting Type":"Surface Mount","-3db Bandwidth":"7 MHz","Amplifier Type":"Audio","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"950µA","Number of Circuits":"1","Current - Input Bias":"200 pA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"9.2 MHz","Voltage - Input Offset":"20 µV","Supplier Device Package":"8-VSSOP","Current - Output / Channel":"31 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.53","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.53000","currency":"USD"},{"qty":10,"price":"$3.17300","currency":"USD"},{"qty":25,"price":"$2.99960","currency":"USD"},{"qty":100,"price":"$2.59970","currency":"USD"},{"qty":250,"price":"$2.46640","currency":"USD"},{"qty":500,"price":"$2.21312","currency":"USD"},{"qty":1250,"price":"$1.86648","currency":"USD"},{"qty":2500,"price":"$1.77316","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0583c47aec2a722c84fcdbef29e5d03f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is OPA1637DGKT a differential output op-amp?","answer":"Yes, the output type is differential.

The TLV9351IDCKR is a general-purpose single op amp in a similar package but has rail-to-rail output, not differential output — it is not a functional substitute for driving an ADC differentially.
