How can I eliminate noise from digital output of a latching hall sensor from allegr-micro ( 3175) ?
I/m using it on a BLDC motor to measure speed.
 

use a low pass filter with the cutoff frequency slightly higher than your required maximum frequency

Just For your information we use Hall sensors in our automotive design for the speed measurement and the low pass filter is what we implement :)
 

place a ferrite bead on the digital output.

best regards
