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 (36V)

operational amplifiers (op amps). The LM2902B-Q1

and LM2902BA-Q1 provide outstanding value for

cost-sensitive applications, with features including

low offset (3mV and 2mV 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 0.3mV (typical), and

lower quiescent current of 240μA (typical). High ESD

(2kV, 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.
