Overview
The LM2904AS-13, produced by Diodes Incorporated, is a dual operational amplifier that belongs to the LM2902/LM2904 series. These devices are designed to operate from a single power supply over a wide range of voltages, from 3V to 36V, and can also function with split power supplies. The LM2904AS-13 is characterized by its low power supply current, which is independent of the magnitude of the power supply voltage, and its extended industrial temperature range of -40°C to +125°C. This makes it suitable for various industrial and automotive applications.
