3 Description

The LM2904-Q1, LM2904B-Q1, and LM2904BA-Q1 are industry-standard operational amplifiers that have been qualified for automotive use in accordance to the AEC-Q100 specifications. The LM2904B-Q1 and LM2904BA-Q1 are the next-generation versions of the LM2904-Q1, which include two high-voltage (36 V) operational amplifiers (op amps). The LM2904B-Q1 and LM2904BA-Q1 provide outstanding value for cost-sensitive applications, with features including low offset (3 mV and 2 mV maximum, respectively), common-mode input range to ground, and high differential input voltage capability.

The LM2904B-Q1 and LM2904BA-Q1 simplify circuit design with enhanced features such as unity-gain stability, lower offset voltage of 0.3 mV (typical), and lower quiescent current of 300 µA (typical). High ESD (2 kV, HBM) and integrated EMI and RF filters enable the LM2904B-Q1 and LM2904BA-Q1 devices to be used in the most rugged, environmentally challenging applications for the automotive marketplace.
