Description
The MLX90215 is a Programmable Linear Hall Effect
sensor IC fabricated utilizing silicon-CMOS technology.
It possesses active error correction circuitry which
virtually eliminates the offset errors normally associated
with analog Hall Effect devices. All magnetic response
functions of the MLX90215 are fully programmable for
even greater versatility. The V_OQ (V_OUT@ B=0),
sensitivity, direction of slope and the magnitude of
sensitivity drift over temperature, are all programmable.
The ratiometric output voltage is proportional to the
supply voltage. When using the supply voltage as a
reference for an A/D converter, fluctuations of ±10% in
supply voltage will not affect accuracy. When
programmed for a conventional sensitivity (with a
positive gain), the voltage at the output will increase as
a South magnetic field is applied to the branded face of
the MLX90215. Conversely, the voltage output will
decrease in the presence of a North magnetic field. The
MLX90215 has a sensitivity drift of less than +1%
error, and V_OQ stability drift of less than +0.4% error,
over a broad temperature range.
Note: Static sensitive device, please observe ESD precautions.
