1 The product features a 14-bit rotary position sensor digital angle (interface) and pulse width modulation output.

2 The AS5048A is a 14-bit rotary position sensor (formerly called an encoder) for absolute angle measurement and PWM (= pulse width modulation) at 360 degrees based on contactless magnetic sensor technology full rotation output

3 The device is suitable for shaft applications where a simple two-pole magnet rotates above or below the sensor IC, and the 0-position can be programmed into the device with simple SPI commands. The absolute magnetic angular position resolution is 14 bits = 16384 for position measurement, and each revolution is a serial interface (SPI) with digital values.

4 The AS5048 provides PWM output and SPI or I2C interface to provide absolute angle measurement for the microcontroller. In mechanical design, there is no need to consider the precise pairing of the chip's initial 0-position and the magnetic poles of the magnets it uses. Instead, the solution is: the 0-position can be programmed into the device through simple SPI or I2C commands (no special programming equipment). Memory inside the AS5048.

5 The AS5048 also has a very high operating tolerance, including the deviation from the center position between the chip and the paired magnet, the deviation in the air gap between the chip and the paired magnet, and the temperature change between -40C and +150C. 6 The AS5048 magnetic rotary encoder can provide more accurate measurement than the previous magnetic rotary encoder products from Austrian microelectronics. Its 14-bit measurement analog front-end provides a measurement resolution as low as 0.0219 degrees. Through linearization and averaging by the microcontroller, the angular measurement can be accurate to 0.05 degrees. 1 x Wiring 1 x Magnetic Encoder
