Description

The LM2904-Q1 and LM2904B-Q1 are industry-standard operational amplifiers that have been qualified for automotive use in accordance to the AEC-Q100 specifications. The LM2904B-Q1 is the next-generation version of the LM2904-Q1, which include two high-voltage (36 V) operational amplifiers (op amps). The LM2904B-Q1 provides outstanding value for cost-sensitive applications, with features including low offset (1 mV, typical), common-mode input range to ground, and high differential input voltage capability.

The LM2904B-Q1 simplifies circuit design with enhanced features such as unity-gain stability, lower offset voltage of 1 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 devices to be used in the most rugged, environmentally challenging applications for the automotive marketplace.
