Overview
The LM2904BIPWR, produced by Texas Instruments, is a next-generation version of the industry-standard operational amplifier (op amp) LM2904. This dual operational amplifier is designed to provide high performance and reliability in a wide range of applications. It features two high-voltage (36V) op amps, making it suitable for cost-sensitive applications that require low offset, common-mode input range to ground, and high differential input voltage capability. The LM2904BIPWR simplifies circuit design with enhanced features such as unity-gain stability, lower offset voltage, and lower quiescent current. It is also equipped with high ESD protection and integrated EMI and RF filters, enabling its use in rugged and environmentally challenging environments.
