TMR3102中文资料多维科技数据手册PDF规格书

描述 Description

The TMR3102 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 TMR3102 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.

TMR3102P outputs 12-bit absolute position signal

through SPI communication protocol. At the same

time, it is able to output analog and PWM signals,

with rotational speed up to 20,000 RPM.
