The LM2902-Q1, LM2902B-Q1, and LM2902BA-Q1 are industry-standard operational amplifiers that have been qualified for automotive use in accordance to the AEC-Q100 specifications. The LM2902B-Q1 and LM2902BA-Q1 are the next-generation versions of the LM2902-Q1, which include four high-voltage (36V) operational amplifiers (op amps). The LM2902B-Q1 and LM2902BA-Q1 provide outstanding value for cost-sensitive applications, with features including low offset (3mV and 2mV maximum, respectively), common-mode input range to ground, and high differential input voltage capability.

The LM2902B-Q1 and LM2902BA-Q1 simplify circuit design with enhanced features such as unity-gain stability, lower offset voltage of 0.3mV (typical), and lower quiescent current of 240µA (typical). High ESD (1kV, HBM) and integrated EMI and RF filters enable the LM2902B-Q1 and LM2902BA-Q1 devices to be used in the most rugged, environmentally challenging applications for the automotive marketplace.
