Additional Details

The LA-301ML typically operates from a supply voltage of 2.7V to 5.5V. The output voltage is proportional to the applied magnetic field, with a typical sensitivity of around 1.8 mV/Gauss. The quiescent output voltage is typically half of the supply voltage. The sensor is available in a small SOT-23 package. It has a typical operating temperature range of -40°C to +85°C. This sensor is ideal for applications requiring accurate and reliable magnetic field sensing in a compact form factor. It offers good linearity and low offset drift over the operating temperature range.
