Chip - AC4726 Chip: Inductive Position Specific Encoding Integrated Chip
AC4726 is an inductive position encoder chip specifically optimized for servo motors and industrial automation applications. The single-chip integrated single code channel inductive position sensor requires functions such as transmission and reception analog front-end, ADC, and dedicated digital signal processing, supporting ABZ, PWM, and UVW interfaces for angle output. Combined with optimized sensing coils, it can achieve up to 17 resolution output.
The signal frequency can reach 10kHz, supporting 3 pairs of pole sensors to work at high speed of 8000rpm
Multi level programmable excitation frequency: 2MHz-6MHz
Integrated sine and cosine coil receiving, demodulation, digital encoding, and calibration dedicated circuits
Automatic gain control, adaptive encoder with air gap fluctuation between rotor and stator
Integrate multiple functions:Compensation for independent channel misalignment and gain adaptationEMI filtering anti-interferenceCoil detection, etc
Specialized DSP circuit:Angle calibration of adaptive motor speedLow latency angle noise filteringSupport incremental position encodingSupport ABZ, UVW, PWM outputs
1024 pulse accuracy
