Rail-to-rail output and a 20 V/µs slew rate let it handle fast transients in precision DC and low-frequency AC paths. Supply span from 4.5 V to 36 V covers common industrial and automotive rails without a secondary regulator. The 8-VSSOP package fits tight mixed-signal boards where two channels need matched drift performance. ## 1.5 µV offset — the precision floor for sensor front-ends A 1.5 µV typical input offset voltage and 70 pA input bias current keep error low with high source impedances. ## 14 MHz GBW at 1.3 mA per channel — bandwidth without a power penalty The 14 MHz gain-bandwidth product and 1.3 mA supply current per channel suit multi-channel data-acquisition boards with tight per-channel power budgets. ## Temperature range and supply flexibility Rated for -40°C to 125°C ambient, the OPA2189IDGKT accepts a 4.5 V to 36 V supply span. Surface-mount 8-VSSOP package fits compact PCBs. ## Lifecycle and sourcing The OPA2189IDGKT carries an Active product status with ROHS3 compliance. For current pricing and availability, submit an RFQ — the part is sourced through independent distribution and confirmed at quote time. No direct second-source alternate is listed in the TI documentation, but the TLV9362IDDFR (10.6 MHz, 400 µV offset) is a general-purpose dual that shares the same 4.5 V to 36 V supply range and -40°C to 125°C temperature grade, though its higher offset and lower bandwidth make it a functional alternative only where the 1.5 µV precision floor is not critical.","metaTitle":"TI OPA2189IDGKT Zero-Drift Op-Amp, 14 MHz, 1.5 µV Offset","metaDescription":"TI OPA2189IDGKT dual zero-drift op-amp: 14 MHz GBW, 1.5 µV offset, 20 V/µs slew, rail-to-rail out, -40 to 125°C.","metaKeywords":null},"attributes":{"series":"Zero-Drift","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Zero-Drift","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"20V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"Zero-Drift","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.3mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"70 pA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"14 MHz","Voltage - Input Offset":"1.5 µV","Supplier Device Package":"8-VSSOP","Current - Output / Channel":"65 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.19","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.19000","currency":"USD"},{"qty":10,"price":"$4.66300","currency":"USD"},{"qty":25,"price":"$4.40880","currency":"USD"},{"qty":100,"price":"$3.82080","currency":"USD"},{"qty":250,"price":"$3.62488","currency":"USD"},{"qty":500,"price":"$3.25260","currency":"USD"},{"qty":1250,"price":"$2.74316","currency":"USD"},{"qty":2500,"price":"$2.60600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f20ec9c0ff1659bfd0cf85e48ccba59e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is OPA2189IDGKT suitable for precision sensing?","answer":"Yes.
