General Description

The AS5170 is a high-resolution angular position sensor for precise absolute angle measurement. The AS5170 is available with an analog output interface (AS5170A) or a digital output interface (AS5170B). The latter can be programmed as a PWM or a SENT-compliant output interface.
The AS5170 operates at a supply voltage of 5V, and the supply and output pins are protected against overvoltage up to +20V. In addition the supply pins are protected against reverse polarity up to -20V. The AS5170A and AS5170B are available in the SOIC 8 package.

Magnets cannot be ordered at ams directly. Please find a list of recommended magnet suppliers.
