18-bit AMR encoder IC with 18000 rpm tracking and ±0.3° accuracy
Overview
The SP-SC-005 is a single-chip 18-bit anisotropic magneto resistive (AMR) encoder Micro that integrates the AMR sensing element and ASIC in one package. It provides 0 to 360 degree absolute angle output with ±0.3 degree full-temperature accuracy, less than 2 us latency and support for speeds up to 18000 rpm, with SPI, SSI, ABZ, UVW and PWM outputs. Typical uses are BLDC and servo/stepper motor feedback, UAV and gimbal angle control, and industrial or commercial robot rotary position sensing.
Key highlights
- 18-bit angular resolution with 0.022 degree LSB and 0 to 360 degree absolute output
- ±0.3 degree integral non-linearity across the full -40 C to +125 C range
- Maximum tracking speed of 18000 rpm with under 2 us angle output latency
- SPI, SSI, ABZ, UVW and PWM output interfaces in one device
- 3.0 V to 5.5 V supply with 10 mA active current and 16 ms power-up time
- ESD robustness of ±8000 V HBM and ±2000 V CDM
