LM2904-Q1, LM2904B-Q1 Industry-Standard Dual Operational Amplifiers for  
Automotive Applications  
1 Features  
3 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.
