Overview
The LM2904YST is a low-power, bipolar operational amplifier (op-amp) produced by STMicroelectronics. This component consists of two independent, high-gain operational amplifiers with internal frequency compensation. It is specifically designed for automotive and industrial control systems, operating from a single power supply over a wide range of voltages. The LM2904YST is known for its low power supply drain, which is independent of the magnitude of the power supply voltage, making it suitable for various applications including transducer amplifiers, DC gain blocks, and conventional op-amp circuits in single power supply systems.
