MT6835 . 21-Bit High Accuracy Magnetic Encoder IC. Features and Benefits Based on advanced AMR Technology with 0~360 Full Range Angle Sensing 21-bit Core Resolution with Maximum Rotation Speed Up to 120,000 RPM. Output Propagation Delay <10 us User Auto-Calibration and Distortion Compensation with Target INL< . -40~125 Operating Temperature Range Independent Output Interface: ABZ, UVW General Description PWM and SPI. MagnTek 's rotary position sensor MT6835 . Incremental ABZ Resolution 1~16,384 Pulses is an IC based on advanced AMR. per Revolution User Programmable technology. A rotating magnetic field in the x-y sensor plane delivers two sinusoidal UVW Output Resolution 1~16 Pole-Pairs per output signals which indicating the angle Revolution User Programmable ( ) between the sensor and the magnetic ~ Programmable EEPROM field direction. The sensor is only sensitive to the magnetic field direction in x-y plane as the sensing element output is specially designed to be independent from the magnet field strength.
