Overview
The LM2904MX, produced by Fairchild Semiconductor (now part of ON Semiconductor), is a low-power, dual-operational amplifier. This component is part of the LM158 series, which includes two independent, high-gain, internally frequency-compensated operational amplifiers. These amplifiers are designed to operate from a single power supply over a wide range of voltages, making them versatile for various applications. The LM2904MX is particularly useful in systems where dual power supplies are not available, as it can operate from a single supply voltage and still provide the necessary performance for many operational amplifier circuits.
