Programmable Linear Hall-Effect SensorMLX90251 Melexis
All magnetic response functions of the MLX90251 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, 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 amplifier), 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 Voq over a broad temperature range.
