On-/Off-Axis Inductive Position Sensor with
Sin/Cos Output
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
The AS5715A is a preprogrammed derivative of the AS5715R. This means that the AS5715A is not
programmable. The table below shows how the registers of the AS5715A are programmed:
Register - Content 1Dh - C0h 1Eh - Doh |
The tolerance of the preprogrammed AS5715A gain factor is ± 1dB
