Hi, I was wondering how often the MLX90614 writes new data the RAM registers for TA, TOBJ1 and TOBJ2? Is it based on the settling time for FIR and IIR filters? I want to make sure that our software doesn't sample too often in order to save processing time. Thanks.

Hello,

Yes, the refresh rate depends on FIR and IIR settings.

See this AppNote http://www.melexis.com/Assets/Understanding_MLX90614_on-chip_digital_signal_filters_5272.aspx
