The LM124 series is a quadruple high-gain frequency-compensated operational amplifier designed for single-supply operation over a wide range of voltages. It features 2kV ESD protection, wide supply ranges, low supply-current drain, large common-mode input voltage range, low input bias and offset parameters, large differential input voltage range, and internal frequency compensation.
The LM124/LM224/LM324/LM2902 family consists of four independent, high‑gain, frequency‑compensated operational amplifiers that can operate from a single supply ranging from a few volts up to 32 V (26 V for the LM2902). The devices are suitable for transducer amplifiers, DC amplification blocks, and other conventional op‑amp circuits.
