The MLX90251 is a Programmable Linear Hall-Effect sensor with ratio-metric analog output.
All magnetic response functions of the MLX90251 are fully programmable for versatility and system tolerance reduction (End-Of-Line calibration).
The quiescent output voltage Vog (i.e. Vout @ B=0 Gauss), sensitivity, sensing polarity, the magnitude of sensitivity drift over temperature (TC - 1st & 2nd order), the clamping levels, the thermal Voq drift and the signal bandwidth are all programmable through the connector terminals (Vdd-Vss-Out).
It features active error correction circuitry (quadrature spinning current and chopper-stabilized amplification) which virtually eliminates the offset errors normally associated with Hall-Effect devices. The MLX90251 has a very stable thermal compensation for both the sensitivity and the Vog over the broad temperature range.
