14.4. Identification
Identification number: 48 bits freely useable by Customer for traceability purpose.
14.5. Sensor Front-End
14.5.1. HIGHSPEED Parameter
The HIGHSPEED parameter defines the main frequency for the DSP.
For better noise performance, the Slow Mode must be enabled.
14.5.2. GAINMIN and GAINMAX Parameters
The MLX90333 features an automatic gain control (AGC) of the analog chain. The AGC loop is based on
and it targets an amplitude of 90% of the ADC input span.
In MLX90333BCT, this default target is changed to 64% but can be set to 90% by enabling the parameter
AGCRADIUSTARGET.
The current gain can be read out with the programming unit PTC-04 and gives a rough indication of the
applied magnetic flux density (Amplitude).
GAINMIN & GAINMAX define the boundaries within the gain setting is allowed to vary. Outside this range,
the outputs are set in diagnostic low.
14.5.3. FIELDTHRES_LOW and FIELDTHRES_HIGH Parameters
The strength of the applied field is constantly calculated in a background process. The value of this field
can be read out with the PTC-04 and gives a rough indication of the applied magnetic flux density
(Amplitude).
FIELDTHRES_LOW & FIELDTHRES_HIGH define the boundaries within the actual field strength
(Radius) is allowed to vary. Outside this range, the outputs are set in diagnostic low.
