The LM324B and LM2902B devices are the next-generation versions of the industry-standard operational amplifiers (op amps) LM324 and LM2902, which include four high-voltage (36 V) op amps. These devices provide outstanding value for cost-sensitive applications, with features including low offset (600 µV, typical), common-mode input range to ground, and high differential input voltage capability.

The LM324B and LM2902B op amps simplify circuit design with enhanced features such as unity-gain stability, lower offset voltage maximum of 3 mV (2 mV maximum for LM324BA and LM2902BA), and lower quiescent current of 240 µA per amplifier (typical). High ESD (2 kV, HBM) and integrated EMI and RF filters enable the LM324B and LM2902B devices to be used in the most rugged, environmentally challenging applications.
