What can i use and do i need to consider for implementing a Ultra Low Power Angular Sensor Solution?
The MA780 / MA782 (basically same part in two different packages) are used for low power designs. Essentially, these parts allow you to trade off between sampling rate, resolution, and power consumption. This chart will allow you to see general overview of current consumption for a few sampling rates:
The MA780 is now online: MA780 | 8-Bit to 12-Bit, Low-Power Angle Sensor with Integrated Wake-Up Angle Detection | MPS
And mind the Period Counter feature: see MULTI(1:0) to enable period counting like a multi turn encoder (up and down, configured length of bits: 0 ; 4 ; 6 ; 8 bit of period counting).
