rotary position from 0 to 360 Degrees or linear
displacement, stroke - Figure 2). It enables the
design of novel generation of non-contacting
position sensors that are frequently required for
both heavy-duty and industrial applications.
The MLX90340 reports a programmable
ratiometric analog output signal compatible with
a programmable linear Hall sensor. Through
programming, the MLX90340 provides also a
digital PWM (Pulse Width Modulation) output
characteristic.

3. Description
The MLX90340 is a monolithic sensor IC sensitive
to the flux density applied orthogonally and
parallel to the IC surface.
The MLX90340 is sensitive to the three
components of the flux density applied to the IC
(i.e. Bx, By and Bz). This allows the MLX90340 with
the correct magnetic circuit to decode the
absolute position of any moving magnet (e.g.
