General Description:The TMR3105AP 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 TMR3105AP 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. TMR3105AP outputs 12-bit absolute position signal through SPI communication 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. TMR3105AP also provides inverted UVW output, analog and PWM signals, with rotational speed up to 20,000 RPM.

Features and Benefits:(1)Tunneling magnetoresistance (TMR) technology;(2)Contactless measurement;(3)Available in SPI, ABZ differential, UVW, Analog and PWM interfaces;(4)12-bit absolute position output in SPI mode;(5)Programmable A/B interpolation factors: ×1 to ×1024;(6)Programmable Z pulse width in 1LSB/2LSB/4LSB/180°;(7)Programmable inverted UVW output resolution in 1 to 16 pole-pair;(8)Programmable analog clamping voltage and PWM frequency;(9)Programmable zero position;(10)Angular repeatability <±0.2°;(11)Speeds up to 20,000 RPM;(12)Adaptive supply voltage: 3.0 V to 5.5 V.

Applications:(1)Contactless angular position measurement;(2)Brushless motor position sensing;(3)Rotary speed sensing;(4)Robotics.
