14.4. Filter

Parameter

Value

FILTER

0, 1

The MLX90366 features a filter that is enabled when FILTER = 1.

The filter is of type “moving average”. It averages the two most recent internal angle values.

When the filter is enabled, the SENT data holds the average of the two most recent internal angles.

We recommend to enable the filter, in order to benefit from a noise reduction of 30% compared to the

case FILTER = 0. Given that two angle values are computed per each SENT frame, the latency increases

in this case only marginally.

Filter = 0 corresponds to no filtering, and may be selected to optimize the latency (by about 10%),

whenever the latter is system-critical (e.g. stability of a close-loop system).

14.5. Diagnostic Features

Refer to Application_note_Diagnostic_Behavior_90366 for EE_CRC_Enable function description and for

Diagnostic features which can be enabled at user.

14.6. EEPROM endurance

Although the EEPROM is used for Calibration Data Storage (similarly to an OTPROM), the MLX90366

embedded EEPROM is qualified to guarantee an endurance of minimum 1000 write

cycles at 125˚C for

engineering/calibration purpose.
