AS5140H
10-Bit 360?Programmable Magnetic Rotary Encoder For High
Ambient Temperatures

Revision 1.4

Data Sheet
1 General Description
The AS5140H is a contactless magnetic rotary encoder for accurate
angular measurement over a full turn of 360?and over an extended
ambient temperature range of -40篊 to +150篊.
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 indication of the
magnets angular position with a resolution of 0.35?= 1024 positions
per revolution. This digital data is available as a serial bit stream and
as a PWM signal. Furthermore, a user-programmable incremental
output is available.
An internal voltage regulator allows the AS5140H to operate at either
3.3V or 5V supplies.
The AS5140H is pin-compatible to the AS5040; however it uses low-
voltage OTP programming cells with additional programming
options.
