AH910W is a high-performance Hall effect isolated linear current sensor chip that can more effectively measure AC or DC currents, and can be widely used for AC or DC current detection in industrial, commercial, and communication systems. The AH910W series integrates a high-precision, low noise linear Hall circuit and a low impedance main current loop wire internally. When the sampling current flows through the main current loop, the magnetic field generated by it induces corresponding electrical signals on the Hall circuit. After the signal processing circuit outputs a voltage signal, the product output is strictly proportional to the measured current value.

The linear Hall circuit is based on the low offset of BCD technology, and the chopper stable Hall chip can provide accurate proportional voltage, which is accurately calibrated during manufacturing. When the applied current flows through the internal current conduction path (from pins 123 and 4 to pins 5,6,7 and 8), the output of the chip has a positive slope (>VOQ). The typical internal resistance value of this conductive path is 0.75m Ω, which can achieve low energy consumption. The terminals (pins [to 8) of the conductive path are Galvanic isolation from the signal lines (pins 9 to 16). This allows the AH910W current sensor IC to be used in high-end current detection applications without the need for other expensive isolation technologies. This series provides customers with S0P16W packaging that meets RoHS requirements
