LM2904-Q1, LM2904B-Q1  
SLOS414J – MAY 2003 – REVISED FEBRUARY 2021  
LM2904-Q1, LM2904B-Q1 Industry-Standard Dual Operational Amplifiers for  
Automotive Applications  
1 Features  
3 Description  
•
AEC Q-100 qualified for automotive applications  
– Temperature grade 1: –40°C to +125°C  
– Device HBM ESD classification 2  
– Device CDM ESD classification C5  
Wide supply range of 3 V to 36 V (LM2904B-Q1)  
Supply-current of 300 µA per channel (LM2904B-  
Q1, typical)  
Unity-gain bandwidth of 1.2 MHz (LM2904B-Q1)  
Common-mode input voltage range includes  
ground, enabling direct sensing near ground  
Low input offset voltage of 3 mV at 25°C  
(LM2904B-Q1, maximum)  
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.
