STMicroelectronics IIS2MDC 3-Axis Digital Magnetic Sensor
STMicroelectronics IIS2MDC 3-Axis Digital Magnetic Sensor has up to a ±50 gauss magnetic field dynamic range with a 16-bit data output. The IIS2MDC has an I2C serial bus interface to support standard (100kHz), fast mode (400kHz), fast mode plus (1MHz), and high-speed (3.4MHz).
The sensor also has an SPI serial standard interface and can be configured to generate an interrupt signal for magnetic field detection. The IIS2MDC is housed in a plastic land grid array package (LGA) and operates over an extended -40°C to +85°C extended temperature range.
