LM2904-Q1/LM2904B-Q1 Dual Operational Amplifiers Texas Instruments LM2904-Q1/LM2904B-Q1 Dual Operational Amplifiers (Op Amps) are industry-standard operational amplifiers that have been qualified for automotive use per the AEC-Q100 specifications. The LM2904B-Q1 is the next-generation version of the LM2904-Q1, which includes two high-voltage (36V) operational amplifiers (op amps). The LM2904B-Q1 provides outstanding value for cost-sensitive applications, with features including low offset (1mV, 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, a lower offset voltage of 1mV (typical), and a lower quiescent current of 300µA (typical). High ESD (2kV, 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.
