Functional Diagram

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_OQstability drift of less than +0.4% error,

over a broad temperature range.
