The 2.5 MHz gain-bandwidth product and 5 V/µs slew rate (cite:,) support signal bandwidths up to a few hundred kilohertz with reasonable settling — suitable for sensor conditioning, data-acquisition front-ends, or active filters in 4-20 mA loops. Input offset voltage is 5 µV typical (cite:), and input bias current is 5 pA (cite:) — the low offset and bias errors mean the circuit sees the sensor signal, not the amplifier's own drift. Rail-to-rail output (cite:) preserves dynamic range when operating from a single 5 V or 3.3 V rail. Supply current is 140 µA per quad (cite:), or 35 µA per amplifier — a low-power choice for multi-channel systems where the op-amp bank's quiescent draw must stay under a few milliamps. Each channel can deliver 65 mA output drive (cite:), enough to drive an ADC input or a moderate cable capacitance. The 4.5 V to 36 V supply span (cite:,) covers single-supply 5 V and 12 V rails as well as ±15 V dual supplies — the same BOM position works across multiple board variants without a respin. ## Temperature grade and deployment environment Rated for -40°C to 125°C operating temperature (cite:) — this is the industrial and automotive ambient range. The part can sit in an outdoor enclosure, an engine bay (with derating), or a factory-floor control cabinet without the output parameters drifting outside the datasheet limits. Surface-mount 14-SOIC footprint (cite:) — standard 3.90 mm body width, compatible with common PCB layouts for quad op-amps. Available in Tape & Reel for automated pick-and-place or Cut Tape for prototype runs (cite:). ## Sourcing posture — quoted per BOM quantity The OPA4191IDR is sourced through independent distribution channels. Availability and current pricing are confirmed at RFQ time against the buyer's line-item quantity (cite:,). No stock-holding claim is made; the part is quoted to order.","metaTitle":"OPA4191IDR CMOS Quad Op-Amp, 2.5 MHz, 14-SOIC","metaDescription":"Active-production OPA4191IDR — 4-channel CMOS op-amp, 2.5 MHz GBWP, 5 µV offset, rail-to-rail output, -40 to 125°C.
