MT6728：Magnetic Encoded Chips - Off-axis magnetic angle encoded ICs
>
MT6728 is a new generation of interpolation subdivision chip for external input sine and cosine signals launched by MagnTek Microelectronics. MT6728 receives differential positive and cosine analog inputs from external inputs, compensates and decodes the input signal, and outputs an AB incremental signal with a maximum resolution of 16,384 pulses/cycle or 65,536 steps/cycle (Z signal can also be obtained from external inputs). At the same time, MT6728 also provides incremental UVW output, and the resolution supports 1~63 poles/cycle. MT6728 provides a 3-wire SPI interface for the host computer or MCU to read the 21-bit angle and position values inside the chip. At the same time, the PWM with a single-line output can also provide angle data with a resolution of 12 bits. The core advantage of the MT6728 is that it provides a simple self-calibration mode on the user side. Users do not need to interact with the MT6728 chip, do not need to refer to the source, and only need to move in a fixed direction for a few cycles to compensate for the misalignment, amplitude and phase of the external input sine and cosine signals.
