AK7452 Absolute Magnetic Encoder
14-Bit High Resolution meets 25,000 rpm Tracking Speed – The Professional Rotary Angle Sensor IC Choice for Advanced BLDC Servo Systems.
// High-Accuracy Monolithic Hall-Effect 16-Pin SOP Portfolio
The High-Speed Absolute Sensing Advantage
The AK7452 represents a premier flagship single-chip solution for space-constrained, high-performance motion control setups demanding absolute angular precision and robust environmental resilience. Engineered by AKM using an advanced monolithic Hall-effect matrix array, this 14-bit magnetic rotary encoder tracks axis positions flawlessly even under dense thermal fluctuations. Housed in a standardized 16-lead SOP footprint, it secures pure, deterministic parallel computing data corridors and high-speed telemetry lines for next-generation brushless DC (BLDC) motors.
- 14-Bit absolute resolution generating 16,384 distinct angular positions per turn
- Supports comprehensive output interfaces: SPI, 12-bit Parallel, UVW, and ABZ incremental channels
- Advanced internal tracking loop calibration neutralizing angular propagation delay errors
Key Performance Advantages
25,000 rpm Tracking
Equipped with an advanced high-speed internal core loop, processing clean angular metrics dynamically even under aggressive high-velocity motor loops.
Versatile Interface Array
Integrates multiple digital buses simultaneously, enabling clean interface bridging to standard SPI drivers, UVW motor phases, or incremental counters.
Contactless Technology
Utilizes zero physical friction sensing mechanics, bypassing optical dust failures and significantly increasing lifetime robustness for factory fieldboards.
