AK09918C Description

Short technical summary and product information.

The AK09918C is a 3-axis electronic compass integrated circuit from Asahi Kasei Microdevices (AKM). It employs high-sensitivity Hall sensor technology to detect terrestrial magnetism along the X, Y, and Z axes. This IC is designed for applications requiring accurate heading information, such as map orientation in smartphones for pedestrian navigation.

 

Key features include a built-in Analog-to-Digital Converter (ADC) providing 16-bit data output for each magnetic component, with a typical sensitivity of 0.15 µT/LSB. The device supports an I2C bus interface, compliant with Standard and Fast modes. It offers various operation modes, including Power-down, Single measurement, Continuous measurement, and Self-test. The operating supply voltage ranges from +1.65V to +1.95V, and it operates within a temperature range of -30°C to +85°C.

 

The AK09918C is housed in a compact 4-pin WL-CSP (Wafer Level Chip Scale Package) with dimensions of 0.8 mm x 0.8 mm x 0.5 mm, making it suitable for space-constrained designs. It also incorporates a self-test function with an internal magnetic source and a magnetic sensor overflow monitor function.
