Alfa Electronics AH950
The AH950 consists of a high-precision, low noise, low temperature drift linear Hall IC, magnetic core, and low insertion resistance (0.12m Ω) current conductor path (located near the mold surface). The applied current flowing through this conductor path generates a magnetic field, which the chip converts into a voltage signal output proportional to the input current. The output voltage of AH950 is provided by the BCDMOS Hall IC with low offset and chopping stability.| Part No. | AH950 |

AH950 Open loop high-precision linear current sensor 1. Product Introduction AH950 series is an open-loop current sensor module based on the Hall effect principle, providing a more economical and accurate solution for AC or DC detection. It is widely used in industrial, commercial, and communication systems for AC or DC current detection. This product can be used for motor control, load detection and load management, power supply and DC-DC converter, Solar inverter, UPS, over-current protection, medium and low power inverter current detection and other applications. According to different current ranges, the output voltage is accurately calibrated internally in the factory. When the applied external current flows through the conduction path (from pin 4 to pin 5), the output of the chip has a positive slope (>VOQ). The typical internal resistance value of this conduction path is 120u Ω, which can achieve low energy consumption. The terminals (pins 4 and 5) of the conductive path are Galvanic isolation from the signal terminals (pins 1 to 3).
