LM2904 Operational Amplifier

LM2904 2-Channel, 1 MHz, general purpose opamp

The LM2904B devices are the next generation versions of the industry-standard operational amplifiers (op amps) LM358 and LM2904, which include two high-voltage (36-V) op amps. These devices provide outstanding value for costsensitive applications, with features including low offset (300 µV, typical), common-mode input range to ground, and high differential input voltage capability. 

The LM2904B op amps simplify circuit design with enhanced features such as unity-gain stability, lower offset voltage of 3 mV (maximum at room temperature), and lower quiescent current of 300 µA per amplifier (typical). High ESD (2 kV, HBM) and integrated EMI and RF filters enable the LM358B and LM2904B devices to be used in the most rugged, environmentally challenging applications.

We have various types of OPAMP IC's. Check our complete collection of OPAMP IC.
