MLX90288 is a SMD programmable linear Hall sensor with a ratiometric analog output targeted for small stroke rotary and linear position sensor applications. It can also be used for slow current sensing application.

All magnetic response functions of the MLX90288 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 MLX90288 has a very stable thermal compensation for both the sensitivity and the Voq over a broad temperature range.
