LM2904 is a low power dual operational amplifier with features such as internal frequency compensation, large DC voltage gain, wide bandwidth, very low supply current, etc. It is designed for automotive and industrial control systems and can operate from a single power supply. It is suitable for transducer amplifiers, DC gain blocks, and other conventional op-amp circuits.
The LM2904 is a low‑power dual operational amplifier designed for automotive and industrial control systems. It features internally frequency‑compensated stages, a large DC voltage gain of 100 dB, wide bandwidth of 1.1 MHz, very low supply current and low input bias and offset currents.
