ams AS5715R Position Sensor
The AS5715A/AS5715R is an inductive sensor IC with differential SIN/COS output for high speed position sensing applications. To fulfill its purpose, the AS5715A/AS5715R device has to be connected to a coil system. The coil system consists of a TX (transmitting) and two RX (receiving) coils typically integrated on a PCB (Printed Circuit Board). The device excites the TX coil with a high frequency voltage. A target above the coil system effects the amount of voltage induced into the RX coils depending on the position of the target. The device senses, demodulates, and amplifies this
voltage. If If the coil system is designed properly, then the device output delivers SIN and COS shaped voltages. An ECU (Electronic Control Unit) can calculate the target position by applying an atan2() function to the SIN and COS output signal. The AS5715A/AS5715R is defined as SEooC (Safety Element out of Context) according ISO26262.
