Features
Single-chip 3D Hall-effect sensor with integrated ADC and SPI interface reduce BOM and PCB size.
Linear position accuracy typically ±0.15mm over 100mm range help achieve more precise linear motor transport systems.
3D Hall-effect sensors with configurable sensitivity ±25mT to ±100mT and ±75mT to ±300mT to help optimize measurement range and accuracy.
Sample rates up to 8 kHz at low latency of 57.5us and 10MHz SPI enable higher speed position control.
Dedicated ALERT pin enables simultaneous start-of-conversion of X,Y,Z axis across multiple 3D Hall-effect sensors.
3D Hall-effect sensors diagnostics features help detect and report both system and device-level failures.
