AEAT-6600-T16
10 to16-Bit Programmable Angular Magnetic Encoder IC
Data Sheet
Description
The Avago AEAT-6600 angular magnetic encoder IC is a
contact less magnetic rotary encoder for accurate angular
measurement over a full turn of 360 degrees.
It is a system-on-chip, combining integrated Hall elements,
analog front end and digital signal processing in a single
device.
To measure the angle, only a simple two-pole magnet,
rotating over the center of the chip, is required. The
magnet may be placed above or below the IC.
The absolute angle measurement provides instant indica-
tion of the magnet’s angular position with a resolution of
0.005° = 65 536 positions per revolution. This digital data
is available as a serial bit stream and as a PWM signal.
An internal voltage regulator allows the AEAT-6600 to
operate at either 3.3 V or 5 V supplies.
