Qualified for Automotive Applications

of low-noise operational amplifiers with e-trim™,

•

AEC-Q100 Qualified With the Following Results:

offering outstanding dc precision and ac performance.

–

Device Temperature Grade 1: –40°C to

Rail-to-rail output, low offset (25

μV maximum), low

+125°C Ambient Operating Temperature

noise (7.5 nV/

√Hz), quiescent current of 950 μA

(maximum), and a 5.5-MHz bandwidth make this part
