ACEINNA MCR1101 Current Sensor ICs are ±5A, ±20A, and ±50A fully integrated bi-directional analog output current sensors. These sensor ICs deliver high accuracy and high bandwidth. The MCR1101 sensor ICs incorporate the Anisotropic Magneto Resistive (AMR) sensor technology that provides inherently low noise, excellent linearity, and repeatability. These sensor ICs are suitable for both high-side and low-side bidirectional current sensing and offer a high bandwidth of 1.5MHz (3dB). The MCR1101 sensor ICs are designed to eliminate sensitivity to stray and common mode magnetic fields. These sensor ICs' inherently low output noise avoids the requirement of additional filtering at low currents.
