LM2904 Low-Power Dual Operational Amplifiers STMicroelectronics LM2904 Low-Power Dual Operational Amplifiers consist of two independent, high-gain operational amplifiers (op-amps) with internal frequency compensation. The LM2904 operates from a single power supply and is designed for automotive and industrial control systems. The op-amps have a large 100dB DC voltage gain with a wide bandwidth of 1.1MHz. The LM2904 has an input common-mode voltage range that includes a negative rail and a differential input voltage range equal to the power supply voltage. Typical applications include transducer amplifiers, DC gain blocks, and all the conventional op-amp circuits which can be easily implemented in single power supply systems.
