Determined by design and characterization; not tested in production.

[2]

Hysteresis error and output noise are included in the Angular Error specification.

Typical values represent 3σ performance unless otherwise specified.

[4]

Angle Error over Lifetime assumes the maximum observed angle error drift due to AEC-Q100 Grade 1 stress, relative to zero hour performance..
