The rail-to-rail output swing preserves dynamic range at low supply voltages, and the 3 mV input offset (typical) is adequate for DC-accurate signal conditioning in this power tier. ## 600 nA supply — what it buys the BOM At 600 nA quiescent current, this op-amp extends battery life in applications where the signal chain is always active. For a 240 mAh coin cell, the op-amp alone draws roughly 0.25% of capacity per year from the quiescent current, leaving nearly all the energy budget for the sensor, MCU, and wireless link. The trade-off is the 10 kHz gain-bandwidth: signals above a few kilohertz will see significant attenuation, so this part fits DC and low-frequency tasks — thermistor conditioning, photodiode amplification with a large feedback capacitor, or bandgap reference buffering — not audio or high-speed ADC drivers. Rail-to-rail output swings to within millivolts of each rail at light loads, and the 27 mA output current per channel can drive modest loads — a reference input, a comparator, or a low-power ADC — directly. The 0.003 V/µs slew rate reflects the nano-power bias; expect 10% to 90% rise times on the order of hundreds of microseconds for a 1 V step, consistent with the 10 kHz GBP. ## Package and environment The -10°C to 60°C operating temperature range targets commercial and indoor environments — office equipment, portable consumer devices, and controlled industrial enclosures — not automotive or extended-industrial duty. The surface-mount package suits automated assembly, and the Tube shipping medium is typical for prototype and low-volume builds. ## Active lifecycle — no end-of-life pressure The part is ROHS3 compliant. For production BOMs, this removes the urgency to qualify a second source now, though the ultra-low-power op-amp market has several pin-compatible alternatives from other vendors if dual-sourcing is required for supply resilience.","metaTitle":"RE46C311S8F op-amp, 10 kHz GBP, 600 nA supply, 8-SOIC","metaDescription":"RE46C311S8F general-purpose op-amp: 10 kHz gain-bandwidth, 600 nA supply current, rail-to-rail output, 1.8 V to 5.5 V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Slew Rate":"0.003V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"600nA","Number of Circuits":"1","Operating Temperature":"-10°C ~ 60°C","Gain Bandwidth Product":"10 kHz","Voltage - Input Offset":"3 mV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"27 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"1.8 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.61","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.61000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/71092d162c6d34b7b4d03dfa555e63fd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can RE46C311S8F be used in battery-powered applications?","answer":"Yes.
