8.2 Application Example II: Low-Power Encoder
Via SSI, the AS5130 will be able to toggle between active mode and low power mode. In active mode, the current consumption is ~15mA and in
low power mode 2mA. The fastest possible startup time from low power mode is 150µs. The AS5130 can be periodically switched between
active and low power mode, the average power consumption depends on the duty cycle. In order to read out the correct data, the active mode
time must be larger than 150µs.

Example: sampling period = one measurement every 10ms.
