ams OSRAM AS5270 Magnetic Angular Position Sensors
ams OSRAM AS5270 Magnetic Angular Position Sensors are 14-bit high-resolution on-axis sensors. The dual-die, high-resolution sensors are available with an analog output interface (AS5270A) or a digital output interface (AS5270B). The digital sensor can be programmed as pulse-width modulation (PWM) or a single-edge nibble transmission (SENT) compliant output interface. The AS5270 operates at a supply voltage of 5V, and the supply and output pins are protected against overvoltage up to +20V. The supply pins are protected against reverse polarity up to -20V. ams OSRAM AS5270 Magnetic Angular Position Sensors are AEC-Q100 Grade 0 qualified and ISO26262 safety-compliant.
