DESCRIPTION

The LM358B and LM2904B devices are the next generation versions of the industry-standard LM358 and LM2904 devices, which include two high-voltage (36-V) operational amplifiers (op amps). These devices provide outstanding value for cost-sensitive applications, with features including low offset(300 µV, typical), common-mode input range to ground, and high differential input voltage capability.

The LM358B and LM2904B devices 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 (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.

The LM358B and LM2904B devices are available in micro-size packages, such as TSOT-8 and WSON,as well as industry standard packages, including SOIC, TSSOP, and VSSOP.
