AEAT-6010/6012 Magnetic Encoder
10 or 12 bit Angular Detection Device
Data Sheet
Description
Avago Technologies’ AEAT-60xx series of magnetic
encoders provides an integrated solution for angular
detection. With ease of use in mind, these magnetic
encoders are ideal for angular detection within 360°.
Based on magnetic technologies, the device is non-con-
tact and ensures reliable operations. It is able to provide
absolute angle detection upon power-up, with a resolu-
tion of 0.0879°(12 bits version) or 0.35°(10bits version),
which is equivalent to 4096 and 1024 positions per rev-
olution respectively. The positional data is provided in
serial bit stream. There is no upper speed limit; the only
restriction is that there will be fewer samples per revolu-
tion as the speed increases.

Figure 3. Integral non-linearity
Di erential non-linearity
Di erential non-linearity (DNL) is the maximum deviation
of the step length from one position to the next.
Integral non-linearity
Integral non-linearity (INL) is the maximum deviation
between actual angular position and the position
indicated by the encoder’s output count, over one revo-
lution. It is de ned as the most positive linearity error
+INL or the most negative linearity error –INL from the
best t line, whichever is larger.
