Dual CMOS op-amp with picoamp bias and rail-to-rail output
Its input bias current is a vanishing 0.002 pA, making it suitable for high-impedance sensor interfaces such as photodiode amplifiers, pH probe buffers, and precision integrators where bias-current-induced offset would otherwise dominate. The rail-to-rail push-pull output stage maximizes dynamic range in single-supply designs operating from 4.75 V to 15.5 V.
The 1.4 MHz gain-bandwidth product sets the usable closed-loop bandwidth: at a gain of 10, expect a -3 dB point around 140 kHz. That covers most industrial sensor conditioning, audio line-level processing, and control-loop filtering. The 0.002 pA input bias current is the standout parameter for high-source-impedance circuits. A 10 MΩ source resistor produces only 20 nV of offset voltage from bias current — negligible compared to the 1 mV input offset voltage. This lets the designer use larger feedback resistors without trading DC accuracy, which is useful in low-power, low-noise photodiode transimpedance amplifiers where the feedback resistor sets the noise gain.
The LMC® series is a mature, well-established family; no PCN or EOL events are flagged in the current record.
