Description | |
The TMR3109 is a contactless, high-precision, and high-speed magnetic rotary encoder sensor, which integrated with tunneling magnetoresistance (TMR) sensors and CMOS digital signal processing circuitry. The TMR3109 senses the single pole-pair magnet rotation above the chip by TMR sensors, collects the rotating magnetic field signal, transmits it to the digital processing unit, and calculates the rotation angle. The TMR3109 supports 3-wire and 4-wire SPI working modes, allowing the client MCU to read 23-bit absolute position information through the SPI protocol. Auto-calibration is available for the TMR3109 to compensate non-linearities caused by imperfect installation. | ![]() |
