3 Description

The LM2902-Q1, LM2902B-Q1, and LM2902BA-Q1

are industry-standard operational amplifiers that have

been qualified for automotive use in accordance to

the AEC-Q100 specifications. The LM2902B-Q1 and

LM2902BA-Q1 are the next-generation versions of

the LM2902-Q1, which include four high-voltage (36

V) operational amplifiers (op amps). The LM2902BQ1

and LM2902BA-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 LM2902B-Q1 and LM2902BA-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 240 μA (typical). High ESD

(2 kV, HBM) and integrated EMI and RF filters enable

the LM2902B-Q1 and LM2902BA-Q1 devices to be

used in the most rugged, environmentally challenging

applications for the automotive marketplace.
