The MX8683 is a 10-bit Digital Output Magnetic Flux Sensor. The device is a complete sampled data subsystem that converts a magnetic flux intensity of ±200 Gauss full scale into a 12-bit format digital output word, 10-bit resolution . The sensor operates as a slave on the serial interface with TTLlevel compatible inputs SDI serial data input , SCK serial clock , and CS* chip select, active low . Terminal SDO is the tri-state serial data output.

An optional exponentially weighted moving average digital filter is included that averages the 10-bit ADC output into a 12-bit output word. The digital filter has a transfer function equivalent to a first order low pass filter.

The full scale trim and/or the digital filter time constant are controllable through the serial I/O interface and are one-time programmable through the serial interface once programmed, the values are loaded at every power-on .

The MX8683 can be mounted onto a PCB or incorporated into a magnetic assembly and then calibrated in-system through the serial interface. The operating voltage range is 4.5V to 5.5V.
