Overview
The LM2904EDR2G is a dual operational amplifier (op-amp) produced by onsemi. This device is part of the LM2904 series, which is known for its low power drain, wide range of supply voltages, and versatility in both single and split supply operations. The LM2904EDR2G is designed to operate from a single power supply ranging from 3.0 V to 32 V or from split power supplies ranging from ±1.5 V to ±16 V. It features a common mode input voltage range that includes the negative supply, eliminating the need for external biasing components in many applications. This op-amp is internally compensated and offers a high DC voltage gain, making it suitable for a variety of applications requiring precision and reliability.
