3. Description
The Melexis MLX90290 is a Second Generation linear
Hall-effect sensor designed in mixed signal CMOS
technology.
The device integrates a voltage regulator, Hall sensor
with advanced offset cancellation system and an
analog output driver, all in a single package.
The Output voltage is proportional to the applied
magnetic field and to the chip supply voltage
(ratiometric). Multiple sensitivity codes & magnet
compensation options exists.
The Output Offset Level (Quiescent Level) at zero
magnetic field equals to 50% of the chip supply
voltage.

CA = Radial Tape for UA (Carton Tape in Ammopack)
BU = Bulk for SE or UA
MLX90290-LUA-AAA-612-CR. This ordering code indicates a 5V supply part in TO92
(UA) component with leads separated to achieve a 2.54mm pitch delivered in Carton
Tape on Reel. The sensitivity corresponds to 25mV/mT and a thermal coefficient of
+2000
ppm/°C to compensate for the magnet thermal drift (assumed to be a ferrite
magnet).
