MT6728 is a new generation interpolation and subdivision chip launched by MagnTek Microelectronics for external input sine and cosine signals. MT6728 receives differential sine and cosine analog inputs from external inputs, and after compensating and decoding the input signal, it can output an AB incremental signal with a maximum resolution of 16384 pulses/cycle or 65536 steps/cycle (Z signal can also be obtained from external inputs); At the same time, MT6728 also provides incremental UVW output, with a resolution support of 1-63 pairs per cycle. MT6728 provides a 3-wire SPI interface for the upper computer or MCU to read the 21 bit angle and position values inside the chip. At the same time, a single line output PWM can also provide angle data with a resolution of 12 bits. The core advantage of MT6728 is that it provides a user-friendly simple self calibration mode. Users do not need to interact with the MT6728 chip for data exchange, do not need a reference source, and only need to move in a fixed direction for several cycles to compensate for the misalignment, amplitude, and phase errors of external input sine and cosine signals.
