TMR3105A
Description
The TMR3105A 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 TMR3105A 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. TMR3105A outputs 12-bit absolute position signal through SPI munication protocol. At the same time, it is able to output A/B phase programmable incremental position signal with 1 to 1024 pulse and programmable zero-point (Z phase) signal. TMR3105A also provides inverted UVW output, analog and PWM signals, with rotational speed up to 20,000 RPM.
