<p>The MT6835 chip is a fourth-generation magnetic angle encoder IC, an upgraded version of the MT6825, based on Anisotropic Magnetoresistive (AMR) technology and proprietary signal processing. It enables absolute angle measurement from 0° to 360°. </p> <p></p> <p>This chip consists of a pair of AMR Wheatstone bridges and a signal processing ASIC circuit. As the magnetic field parallel to the chip surface rotates, it outputs angle signals including ABZ, UVW, and PWM. Users can read 21-bit absolute angle data via a standard 4-wire SPI interface supporting up to 16 MHz clock speed. </p> <p></p> <p>It supports a maximum rotational speed of 120,000 RPM. Applications include high-speed, high-precision closed-loop control systems such as stepper motor control, servo motors with up to 2500-line resolution, and 17-bit absolute value servo motor control. </p> <p></p> <p>Operating voltage: 3.3–5.0 V </p> <p>Operating temperature: –40°C to +125°C </p> <p>Linearity deviation: </p> <p>– Factory calibrated: < ±0.5° </p> <p>– Self-calibrated: < ±0.07° </p> <p>– NLC self-calibrated: < ±0.02° </p> <p></p> <p>System delay: 2 µs to 10 µs </p> <p>SPI interface: 4-wire, up to 16 MHz </p> <p>Incremental ABZ output: configurable resolution from 1 to 8192 lines </p> <p>Incremental UVW output: configurable pole pairs from 1 to 16 </p> <p>PWM output: 12-bit resolution </p> <p></p> <p>Specifications: SPI + ABZ (8192 lines) </p> <p>Color: Black </p> <p>Material: PCB </p> <p></p> <p>Package includes: </p> <p>1 × Magnetic Encoder </p> <p>1 × Magnet</p>
