75 kHz gain bandwidth, 18 µA supply — the low-power op-amp for always-on sensing
The rail-to-rail output stage maximizes dynamic range at low supply voltages, and the 0.002 pA input bias current suits high-impedance sources like photodiodes or pH probes.
Supply range and single-supply operation
The 4.5 V minimum means it does not run from a 3.3 V rail — designs at 3.3 V need a boost converter or a different op-amp. For 5 V or 12 V systems, the rail-to-rail output swings within millivolts of the rails, preserving headroom in low-voltage signal chains.
With a 0.02 V/µs slew rate and 75 kHz gain-bandwidth, this op-amp is optimized for DC and low-frequency signals — thermocouple outputs, strain-gauge bridges, battery monitoring, and audio below 20 kHz. It is not intended for high-speed ADC drivers or video lines. The 40 mA output per channel can drive modest loads like a microcontroller ADC input or a reference buffer.
Temperature grade and environment
The CMOS construction keeps quiescent current stable across temperature, unlike bipolar op-amps that double their supply current at high temperature.
Lifecycle and compliance
The /NOPB suffix indicates lead-free (Pb-free) plating — the same die as the original LMC6041AIM, just with a green finish.
