Product type
MEMS magnetometer ICs are integrated circuits that utilize micro-electromechanical systems technology to measure magnetic fields. These sensors are typically made from silicon and incorporate MEMS fabrication techniques to achieve high sensitivity and compact size. They are commonly used in applications such as navigation, motion tracking, and industrial automation.
| Measurement range | ±1 to ±8 gauss |
| Supply voltage | 1.8V to 3.6V |
| Output type | Digital (I2C or SPI) or Analog |
| Operating temperature | -40°C to +85°C |
| Sensitivity | 0.1 to 1.0 µT/LSB |
When selecting a MEMS magnetometer IC, consider the measurement range and sensitivity required for your application. It's important to specify the output type, whether digital or analog, based on your system's compatibility. Additionally, ensure that the operating temperature range meets your environmental conditions. Certifications and tolerances may also be relevant depending on the industry standards applicable to your project.
