The output stage is push-pull rail-to-rail, allowing the output to swing within millivolts of either supply rail in single-supply designs. Supply span ranges from 4.75 V to 15.5 V, and each channel can source or sink 40 mA. ## 1.5 mA quiescent for four channels — what that means on the rail Total supply current for all four amplifiers is 1.5 mA, which works out to roughly 375 µA per channel. In a battery-powered or multi-channel data-acquisition system, that quiescent draw is low enough to keep the thermal budget comfortable in a 14-SOIC without airflow. The 40 mA per-channel output current gives enough drive for modest loads — think driving an ADC input, a reference buffer, or a small relay — but not for heavy cable or 50-ohm back-termination. If you need more output muscle, plan on a separate buffer stage. ## 0.002 pA input bias — the so-what for sensor front ends The CMOS input stage delivers a typical input bias current of 0.002 pA. That is essentially negligible for most practical circuits — a photodiode amplifier, pH probe buffer, or electrometer front end will see virtually no offset from bias current. The input offset voltage is 1 mV, which is decent for a general-purpose CMOS op-amp but not precision-grade; if you need sub-100 µV offset, you will want an auto-zero or chopper-stabilized part. The combination of picoamp bias and rail-to-rail output makes the LMC660AIMX a natural fit for single-supply sensor conditioning where the signal is small and the supply is 5 V or 3.3 V.","metaTitle":"LMC660AIMX CMOS Quad Op-Amp, 1.4 MHz, Rail-to-Rail Output","metaDescription":"LMC660AIMX quad CMOS op-amp from TI LMC series: 1.4 MHz GBW, 1.1 V/µs slew rate, 0.002 pA input bias, rail-to-rail output, 4.75–15.5 V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"LMC®","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"LMC®","Package":"Bulk","Slew Rate":"1.1V/µs","Output Type":"Push-Pull, Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"CMOS","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.5mA (x4 Channels)","Number of Circuits":"4","Current - Input Bias":"0.002 pA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"1.4 MHz","Voltage - Input Offset":"1 mV","Supplier Device Package":"14-SOIC","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"15.5 V","Voltage - Supply Span (Min)":"4.75 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.05","stockQuantity":0,"priceTiers":[{"qty":147,"price":"$2.05000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/79498edbbf7bab73613b3123b29d86df.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LMC660AIMX rail-to-rail output?","answer":"Yes — the output type is push-pull, rail-to-rail.
