MCA1101 Current Sensor Evaluation Boards ACEINNA MCA1101 Current Sensor Evaluation Boards are designed to evaluate MCA1101 Current Sensor ICs. The MCA1101 current sensor ICs are ±5A, ±20A, and ±50A fully integrated bi-directional analog output current sensors. The MCA1101 evaluation boards incorporate Anisotropic Magneto Resistive (AMR) sensor technology, providing inherently low noise, excellent linearity, and repeatability. These evaluation boards eliminate sensitivity to stray and common mode magnetic fields.
