Sampling Rate

When the TMAG5328 device powers up, the device measures the first magnetic sample and sets the output within the tON time. For the TMAG5328A1D (duty cycled version), the output is latched and the device enters an ultra-low-power sleep state. After each tActive time has passed, the device measures a new sample and updates the output if necessary. If the magnetic field does not change between periods, the output also does not change. While in active mode, the part goes through different steps. The content of the OTP (One-Time-Programmable Memory) is loaded first, and this step takes about 35µs and consumes around 350µA. For the next 5µs, the current source starts up and settles. The part now consumes around 650µA in this step. Finally, the part conducts the Hall sensor conversion for about 25µs and consumes the peak current of around 2mA.

The TMAG5328A1Z (continuous time version) stays active after the tON time has passed (does not go to sleep), enabling a fast signal bandwidth of up to 20kHz (fBW).
