Cjmcu 90393 Mlx90393 Digital Hall Sensor Displacement Angle Rotation 3D Position I2C And Spi Output

SPECIFICATIONS:

-16-bit AD / high integrated digital, micro power consumption

-2.2~3.6V wide and low working voltage

-I2C & SPI (10MHz) output mode

-XYZT (can be selected first) three-dimensional absolute position output

-MCU can communicate directly, very simple application

-Low-cost integrated design

OVERVIEW:

-Miniature QFN package 3x3mm

-In-application run-time programmable functional parameters

-Trade-off between current consumption, speed and signal noise with best-in-class Figure of Merit

-Can be used to measure magnetic XYZ and temperature T or any combination thereof

-Duty cycle between 0.1% and 100% (continuous burst)

-Single measurement mode, burst mode and wake-up on change mode

-SPI slave and/or I2C slave with 2 bits HW addressing and 5 bits SW
