STMicroelectronics LM2904W Low Power Dual Operational Amplifier Datasheet
The document describes the LM2904W, a low-power dual operational amplifier designed specifically for automotive and industrial control systems. It features two independent, high-gain amplifiers that are internally frequency compensated and operate from a single power supply over a wide voltage range (3V to 30V). Key characteristics include very low supply current of 500 µA per channel, large DC voltage gain of 100 dB, and an input common-mode voltage range that includes the negative rail.
The datasheet details absolute maximum ratings, electrical characteristics such as input offset voltage, slew rate, and gain bandwidth product. It also provides schematic diagrams, pin connections for various packages (DIP8, SO-8, TSSOP8), and graphical representations of frequency response, output swing, and current limiting behavior under different conditions.
