Overview
The LM2904AQM8-13 is a dual operational amplifier (op-amp) produced by Diodes Incorporated. It is part of the LM2904Q series, which includes automotive-compliant dual and quad operational amplifiers. These devices are designed to operate from a single power supply over a wide range of voltages (3V to 36V) and can also operate from split power supplies (±1.5V to ±18V). They are characterized by their low input offset voltage, low power supply current, and high gain, making them suitable for various applications in automotive and industrial environments.
