Overview
The LM2904QM8-13 is a part of the LM2904Q series of operational amplifiers produced by Diodes Incorporated. These devices are automotive-compliant, dual operational amplifiers designed to offer high gain and very low input offset voltage. They are suitable for a wide range of applications, particularly in the automotive sector, due to their robust performance and compliance with AEC-Q100 Grade 1 standards.
The LM2904Q series operates from a single power supply over a wide voltage range (3V to 36V) or from dual supplies (±1.5V to ±18V). These amplifiers are known for their low power supply current, which is independent of the supply voltage, and their ability to handle a wide input common-mode voltage range that includes ground.
