The TMR3110 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 TMR3110 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 TMR3110 supports 3-wire and 4-wire SPI working modes, allowing the client MCU to read 23-bit absolute position information through the SPI protocol. Additionally, the chip also provides a 12-bit resolution PWM output interface, with the PWM frequency configurable in four levels according to customer requirements.

It is able to output A/B phase programmable incremental position signal with 1 to 4096 pulse and programmable zero-point (Z phase) signal. TMR3110 also provides inverted UVW output, analog and PWM signals, with rotational speed up to 40,000 RPM. 

The TMR3110 can self-calibrate to compensate non-linearities caused by imperfect installation.
