The Pololu ACS72981LLRATR-100B3 Current Sensor Large Carrier -100A to +100A, 3.3V is a sophisticated Hall effect-based sensor designed for measuring bidirectional currents ranging from -100 A to +100 A. It operates at a nominal voltage of 3 V and features a low-resistance current path with a high bandwidth of 250 kHz, ensuring rapid response times. The sensor utilizes a differential Hall sensing mechanism to minimize the impact of external magnetic fields on measurements. It provides a ratiometric analog voltage output proportional to both AC and DC currents, with integrated digital temperature compensation for enhanced accuracy across varying temperatures. The carrier board is engineered with multiple copper layers to reduce power loss and improve heat dissipation, and it is compatible with standard solderless breadboards, accommodating high-current applications. Note: The product is intended for use below 30 V, and exceeding temperature or current limits can cause permanent damage to the sensor.
