... The MLX90277 sensors also have an additional stage, Fine Gain, for fine tuning the Sensitivity. The stage (parameter FG) follows the RG and provides a 10 bit adjustment. The small signal gain of the FG is within 1.0 and 2.5. The RG and FG parameters are adjusted in the application to calibrate the sensitivity (gain) and output slope transfer characteristic of the device ...

... Filter (FILTER) Each die of the MLX90277 includes two programmable low-pass filters located within the chopper amplifier stages. The two low-pass filters are controlled through a 4 bit parameter, FILTER. The FILTER value 0 corresponds to minimum filtering, maximum speed (impulse response time), and maximum output noise. The value 15 provides the maximum filtering, minimum speed, and minimum output noise ...
