The AS5045-ASSU is a 12bit programmable magnetic rotary encoder in 16 pin SSOP package. This contactless magnetic rotary encoder is used for accurate angular measurement over full turn of 360°. It is a system on chip combining integrated hall elements, analogue front end and digital signal processing in a single device. To measure angle, only simple two pole magnet rotating over centre of the chip is required. The magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of magnet"s angular position with resolution of 0.0879° = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal. An internal voltage regulator allows the AS5045 to operate at either 3.3V or 5V supplies.
● Two digital 12bit absolute outputs (serial interface and pulse width modulated output)
● Supply voltage range from 4.5 to 5.5V at pin VDD5V
● User programmable zero position
● Failure detection mode for magnet placement monitoring and loss of power supply
● Red, yellow and green indicators display placement of magnet in Z axis
● Serial read out of multiple interconnected AS5045 devices using daisy chain mode
● Tolerant to magnet misalignment and airgap variations
● Wide ambient temperature range from - 40°C to 125°C
● Ideal for applications in harsh environments due to contactless position sensing
● No calibration required
