The MLX90215 is a programmable linear Hall-effect sensor IC with ratiometric analog output. All magnetic response functions of the MLX90215 are fully programmable for versatility and system tolerances reduction (End-of-Line Calibration). The output quiescent voltage Voq (i.e. Vout @ B = 0 Gauss), sensitivity, the magnitude of sensitivity drift over temperature (TC), the clamping levels are all programmable through the connector terminals (Vdd-Vss-Out). It features active error correction circuitry (quadrature spinning current and chopper-stabilized amplifier) which virtually eliminates the offset errors normally associated with Hall-effect devices. The MLX90215 has a very stable thermal compensation for both the sensitivity and the Voq over a broad temperature range.

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.
