600 nA supply, 14 kHz GBP — the battery-life benchmark
The Microchip MCP6041-I/P is a single general-purpose CMOS op-amp built for one job: stretching battery life in DC or near-DC signal conditioning. Its 600 nA typical supply current is the headline number — an order of magnitude below a standard LM358's 500 µA quiescent, which is why it shows up in portable sensor interfaces, electrochemical gas detectors, and single-cell-powered threshold comparators. The 14 kHz gain-bandwidth product sets the signal ceiling: this is a DC-to-slow-slew part, not an audio amplifier or a fast ADC driver. Input bias current is 1 pA, preserving accuracy from high-impedance sources like photodiodes or pH probes.
Rail-to-rail output with 1.4 V to 6 V supply
The output swings rail-to-rail, so a 1.5 V alkaline cell or a 3.6 V lithium primary can drive the output to within millivolts of the rails — useful when the downstream ADC or comparator has no headroom. The supply span runs from 1.4 V minimum to 6 V maximum, covering two-series alkaline, single Li-Po, or regulated 3.3 V / 5 V rails. Input offset is 3 mV typical, adequate for ratiometric sensing where a few mV of error is tolerable; for precision weigh-scale or thermocouple paths, a chopper-stabilized part would be the better call.
Through-hole 8-DIP — breadboard and legacy through-hole fit
The MCP6041-I/P comes in an 8-pin DIP (0.300" body, 7.62 mm pitch) with through-hole leads, supplied in tube. This package is the breadboard-friendly choice for prototyping, one-off test fixtures, or retrofitting a through-hole PCB that cannot migrate to SMD.
