The LM2904ST is an operational amplifier (op-amp) produced by STMicroelectronics. It is an internally compensated, low-power, quad op-amp, providing high input impedance, wide gain bandwidth and low noise. This versatile device is easy to use and is suitable for many applications. It is available in 8-pin SOIC, 8-pin TSSOP, PDIP and MLP/QFN packages. The LM2904ST is designed to operate from both single or dual 5V or 3V supplies, making it suitable for a wide range of systems. The input common-mode voltage range does not include the negative supply rail, allowing for the use of single supplies. The device offers high input common-mode rejection ratios, making it ideal for use in systems with noisy environment. The LM2904ST operates at frequencies up to 1 MHz and offers good signal-to-noise performance.
