LM124W

The LM324B and LM2902B devices are the next-generation versions of the general-purpose operational amplifiers LM324 and LM2902, which include four high-voltage (36V) operational amplifiers. These devices offer excellent value for cost-sensitive applications, with features including low offset voltage (600μV, typical), ground-referenced common-mode input range, and high differential input voltage capability. The LM324B and LM2902B operational amplifiers simplify circuit design with enhanced features such as unity-gain stability, lower offset voltage (3mV maximum; 2mV maximum for LM324BA and LM2902BA), and lower quiescent current (240μA per amplifier, typical). High ESD (2kV, HBM) and integrated EMI and RF filters support the use of the LM324B and LM2902B devices in more demanding and environmentally challenging applications.
