Description:

The LM324B and LM2902B devices are thenext-generation versions of the industry-standardoperational amplifiers (op amps) LM324 and LM2902,which include four high-voltage (36V) op amps.These devices provide outstanding value for costsensitive applications, with features including lowoffset (600µV, typical), common-mode input range toground, and high differential input voltage capability.The LM324B and LM2902B are unity-gain stableand achieve a low offset voltage maximum of 3mV(2mV maximum for LM324BA and LM2902BA) andquiescent current of 240µA per amplifier (typical).High ESD (2kV HBM and 1.5kV CDM) and integratedEMI and RF filters enable the LM324B andLM2902B devices to be used in the most rugged,environmentally challenging applications.The LM324B and LM2902B can drop-in replace allversions of the LM224, LM324, and LM2902 devices.
