MLX90251
Hall Effect Sensor IC from Melexis Semiconductors
Features
The MLX90251 is a programmable linear hall effect sensor IC fabricated from silicon-CMOS technology and posesses active error correction circuitry which virtually eliminates the offset errors normally associated with analog Hall Effect devices.
All magnetic response functions of the MLX90251, including the quiescent voltage, sensitivity, direction of slope and the magnitude of sensitivity drift over temperature, the clamping level, bandwith and the quiescent voltage temperature-drift are all programmable.
The ratiometric output voltage is proportional to the supply voltage, so when using the supply voltage as a reference for an A-to-D Converter, fluctuations of +10% in supply voltage will not affect accuracy.
When programmed for conventional sensitivity ( with a positive gain ), the voltage at the output will increase as a South-pole magnetic field is applied to the marked side of the MLX90251. Conversely, the voltage output will decrease in the presence of a North-pole magnetic field.
The MLX90251 has a very stable thermal compensation for both the sensitivity and the quiexcent voltage over a broad temperature range.
