With a gain-bandwidth product of 9 kHz and supply current of 450 nA, it fits into battery-powered sensor interfaces, wearable health monitors, and remote IoT nodes that run for years on a coin cell. The rail-to-rail output stage lets it swing close to the supply rails in single-supply designs from 1.4 V to 6 V. ## 450 nA supply — the battery-life decision At 450 nA quiescent, this part draws less than many op-amps' input bias current. In a 3 V system with a 200 mAh coin cell, the amplifier alone adds under 0.5% annual drain — negligible for a continuous-monitoring loop. The trade-off is bandwidth: the 9 kHz GBWP limits the part to DC-precise amplification, sub-audio filtering, and low-frequency signal conditioning. For a thermistor bridge or a photodiode front-end sampling at a few Hz, it is a natural fit. ## 1 pA input bias — high-impedance sensor front-end The 1 pA typical input bias current preserves signal integrity from high-source-impedance sensors like pH probes, pyroelectric detectors, and capacitive humidity elements. Combined with the 4.5 mV input offset voltage, the part can resolve microvolt-level changes when used with a precision reference and appropriate gain staging. The SOT-23-5 package keeps board area small, and the surface-mount footprint suits automated assembly lines. ROHS3 compliant for global regulatory coverage.","metaTitle":"MCP6441T-E/OT — 9 kHz, 450 nA Op-Amp, SOT-23-5","metaDescription":"Microchip MCP6441T-E/OT general-purpose op-amp: 9 kHz GBWP, 450 nA supply, rail-to-rail output, SOT-23-5, -40°C 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":"0.003V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Current - Supply":"450nA","Number of Circuits":"1","Current - Input Bias":"1 pA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"9 kHz","Voltage - Input Offset":"4.5 mV","Supplier Device Package":"SOT-23-5","Voltage - Supply Span (Max)":"6 V","Voltage - Supply Span (Min)":"1.4 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.82000","currency":"USD"},{"qty":25,"price":"$0.67840","currency":"USD"},{"qty":100,"price":"$0.64500","currency":"USD"},{"qty":3000,"price":"$0.64500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/38a4c49982acf84762f42db9630d1605.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MCP6441T-E/OT and the MCP6291T-E/MS?","answer":"The MCP6291T-E/MS is a 10 MHz GBWP, 1 mA supply op-amp — a completely different power/speed tier.
