MT6826S 15-Bit High-Resolution, High-Precision Magnetic Angle Encoder IC
Product Overview
The MT6826S is a new generation of high-speed, high-precision angle encoder ICs based on advanced Anisotropic Magnetoresistance (AMR) technology. It offers absolute angle position detection from 0-360 with 15-bit resolution and high accuracy. The chip integrates two pairs of AMR Wheatstone bridges and a high-performance signal processing circuit, enabling robust performance with lower requirements for magnet processing and mounting accuracy. It supports various output modes including incremental ABZ, incremental UVW, PWM absolute value, and 4-wire SPI bus, making it suitable for a wide range of applications such as absolute angle position sensing, brushless DC motor control, servo motor control, and closed-loop stepper motor control.
