Supply current draws 100 µA, making it suitable for loop-powered or battery-operated transmitters. The output stage is rail-to-rail, but the input common-mode range does not extend to the positive rail — a typical fit constraint for single-supply designs below 5 V. An input offset voltage of 1 µV max lets the designer skip the trim potentiometer and the calibration step in production. For a bridge sensor or shunt-based current monitor, that offset translates directly into a DC error at the output amplified by the closed-loop gain. At a gain of 100, 1 µV of input offset becomes 100 µV of output error — negligible in most 12-bit systems. The 150°C rating covers under-hood automotive, downhole instrumentation, and industrial engine-bay environments, though note the part carries no AEC-Q100 grade — the temperature spec alone is not a qualification. ## 550 kHz GBW and 100 µA supply — design budget trade-off The 550 kHz gain-bandwidth product sets the usable closed-loop bandwidth: at a gain of 10, expect about 55 kHz of small-signal bandwidth. That is enough for 60 Hz rejection loops, low-frequency ADC anti-aliasing, and sensor conditioning, but not for switch-mode current sensing or high-speed data acquisition. The 100 µA supply current is the trade-off — this is a micropower part. Compare to a general-purpose op-amp like the TLV9351IDCKR, which offers 3.5 MHz GBW but draws 600 µA typical. The OPA187ID wins in battery-powered and loop-powered designs where every microamp counts; the TLV9351IDCKR wins where more bandwidth is needed and the power budget allows it. The output swings rail-to-rail, which preserves dynamic range in low-voltage single-supply systems — a 5 V rail delivers a 0 V to 5 V output swing into a light load. The input common-mode range, however, stops 1.1 V below the positive rail (typical for a zero-drift architecture), so at 5 V supply the input cannot exceed about 3.9 V. This rules out high-side current sensing on a 5 V rail unless the shunt voltage is level-shifted. The Zero-Drift series includes several channel-count and bandwidth variants; the OPA187ID is the single-channel 8-SOIC option.","metaTitle":"OPA187ID Zero-Drift Op-Amp, 1 µV Offset, 550 kHz GBW","metaDescription":"Texas Instruments OPA187ID zero-drift op-amp: 1 µV max input offset, 550 kHz GBW, 100 µA supply, rail-to-rail output, -40°C to 150°C.","metaKeywords":null},"attributes":{"series":"Zero-Drift","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"Zero-Drift","Package":"Tube","Slew Rate":"0.2V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"Zero-Drift","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"100µA","Number of Circuits":"1","Current - Input Bias":"100 pA","Operating Temperature":"-40°C ~ 150°C (TA)","Gain Bandwidth Product":"550 kHz","Voltage - Input Offset":"1 µV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"30 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.02","priceTiers":[{"qty":1,"price":"$3.02000","currency":"USD"},{"qty":10,"price":"$2.71100","currency":"USD"},{"qty":25,"price":"$2.55720","currency":"USD"},{"qty":100,"price":"$2.17880","currency":"USD"},{"qty":250,"price":"$2.04580","currency":"USD"},{"qty":500,"price":"$1.79008","currency":"USD"},{"qty":1000,"price":"$1.48320","currency":"USD"},{"qty":2500,"price":"$1.44750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6520ccb89b8d055d4ba086beba3f6270.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA187ID/alternatives.json"},"ai":{"faq":[{"question":"Is the OPA187ID a rail-to-rail output op-amp?","answer":"Yes, the OPA187ID has a rail-to-rail output stage.
