(*) – The conversion time depends on the programmed initialization time and on the ADC options.
(**) For the Read/Write Internal Devices commands, the delay depends on the nature of the so-called Internal Device: (Register, EE-
Latch bank, ADC,…)
(***) – See the power management chapter to know when the MLX90129 may be in sleep mode
