The MLX90215 is a Programmable Linear Hall Effect sensor IC fabricated utilizing silicon-CMOS technology. It posesses active error correction circuitry which virtually eliminates the offset errors normally *ociated with *og Hall Effect devices. All magnetic response functions of the MLX90215 are fully programmable for even greater versatility.

The VOQ (VOUT@ 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 VOQ stability drift of less than 0.4% error, over a broad temperature range.
