Its 9 µV maximum input offset voltage and 2 pA input bias current suit it for precision DC signal chains where drift over temperature would otherwise require periodic system calibration — weigh scales, bridge transducers, thermocouple amplifiers, and photodiode front-ends. The 10 MHz gain-bandwidth product and 9.5 V/µs slew rate are unusual for a zero-drift topology, letting it handle audio-band anti-aliasing filters or fast sensor excitation loops without switching artifacts typical of chopper-stabilized designs. Rail-to-rail output swings within millivolts of each supply, preserving dynamic range at low voltages. Each channel can source or sink 40 mA — enough to drive an ADC reference input or a small relay coil through a series resistor. The extended industrial temperature range qualifies the part for under-hood automotive, factory-floor automation, outdoor telecom nodes, and engine-bay electronics where commercial 85°C parts would derate or fail. The active product status means Microchip continues to manufacture it — no last-time-buy clock is running, and it remains eligible for new-design qualification. ## Sourcing posture: quoted to order This is a current-production, active-listed Microchip part.","metaTitle":"MCP6V91UT-E/OT Zero-Drift Op-Amp, 9 µV Offset, 10 MHz","metaDescription":"Microchip MCP6V91UT-E/OT zero-drift op-amp: 9 µV input offset, 10 MHz GBWP, 9.5 V/µs slew rate, rail-to-rail output, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"9.5V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"Zero-Drift","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Current - Supply":"1.1mA","Number of Circuits":"1","Current - Input Bias":"2 pA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"10 MHz","Voltage - Input Offset":"9 µV","Supplier Device Package":"SOT-23-5","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.4 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.93","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.93000","currency":"USD"},{"qty":25,"price":"$1.60080","currency":"USD"},{"qty":100,"price":"$1.48500","currency":"USD"},{"qty":3000,"price":"$1.48500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/910207b986b3afc2e8b2a68f647411ae.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is MCP6V91UT-E/OT's listed slew rate?","answer":"The datasheet specifies a 9.5 V/µs slew rate for the MCP6V91UT-E/OT, which is unusually fast for a zero-drift amplifier and supports moderate-speed signal conditioning up to roughly 1 MHz closed-loop gain."},{"question":"Is MCP6V91UT-E/OT a good replacement for OPA333?","answer":"Both are single-supply zero-drift op-amps in SOT-23-5 packages, but the MCP6V91UT-E/OT offers a 10 MHz gain-bandwidth versus OPA333's 350 kHz, and a 9.5 V/µs slew rate versus 0.16 V/µs — a significant speed upgrade.
