product detail
If you need a data sheet, please leave a message to let us know, thank you !
Complete rotary transformer (encoder) application
Support 12Bit/10Bit per electrical angle accuracy.
Highly integrated rotary transformer application, controllable excitation voltage and excitation frequency, flexible adaptation to different sensors.
Supports angle output and speed output, which can be read via parallel interface or SPI serial interface.
Data communication CRC check.
3.3-8V wide power supply (typical operating current is 265mA for 5V power supply).
Provide a reference program.
common problem:
Q: Can I output speed and angle data at the same time?
A: Speed and angle data can be read through SPI. VA0/VA1 is selected by patch resistor jumper. Therefore, the parallel interface can only output angle or speed. In addition, the angle can be read through the parallel port and the SPI interface can be used to read the speed.
